No full textTsounkranaglenea gen. nov. Type species: Tsounkranaglenea hefferni sp. nov. Diagnosis. It is mostly similar to Glenea by the lateral elytral carinae and truncate elytral apex, but can be distinguished by the elongated, bended and rake-shaped sternite VII. In fact, it differs from all other saperdine genera by the peculiar sternite VII in males. It also differs from Paraglenea Bates, 1866, Heteroglenea Gahan, 1897 (as defined in Lin, Montreuil et al, 2009) and Pareutetrapha Breuning, 1952 by the male claws of fore and hind legs simple instead of appendiculate or bifid and elytral apex truncated with sharp teeth instead of rounded or slightly truncated without sharp teeth. It also differs from Eumecocera Solsky, 1871 and Stenostola Dejean, 1835 by the elytra with lateral carinae and male claws of fore and hind legs simple instead of appendiculate or bifid. The combination of the following characters makes the new genus easily separable from other saperdine genera: prothorax without lateral tubercles, elytra with distinct lateral carinae, elytral apex truncated with long spines at outer angle, male claws with appendiculated tooth only in mesotarsi and female claws all simple, male sternite VII elongated and bended into a rake-shape. Description. Small-sized (under 15 mm). Head not broader than prothorax. Eyes deeply emarginate, not divided, lower eye lobe much vertically longer than (male) to subequal to (female) gena. Antennae longer than body, in male slightly longer than female, basal segments fringed with sparse setae, scape slightly expanded, second antennomere short, third antennomere always the longest, 4 th antennomere subequal to (female) to slightly longer than (male) scape, 4 th to 10 th slightly and gradually decreasing in length except 11 th being slightly longer than 10 th. Prothorax cylindrical, without lateral tubercles, slightly narrowed around basal fifth. Elytra subparallel, truncated apically, with sharp teeth at both inner and outer angles, each with two distinct lateral carinae starting from the base and combined into apical outer tooth (Figs 1b, 11b). Procoxal cavity closed posteriorly (Fig. 11c), mesocoxal cavity open to mesepimeron, metanepisternum more than twice as wide anteriorly as posteriorly. Protarsi with first segment expanded in male (Fig. 1a), mesotibiae with an oblique groove with setae (Fig. 1b), hind femur reaching fifth abdominal segment, hind tarsi with first segment longer than the following two combined. Male claws: only anterior claws of mesotarsi appendiculate with small teeth (Figs. 4–5), posterior claws of mesotarsi without teeth, and claws of pro- and metatarsi simple. Females claws simple (Figs. 11 a-11b). Male sternite VII elongated and bent into a rake-shape (Figs. 1–3), female sternite VII with a median groove (Fig. 11c). Male terminalia. Apex of male tergite VIII emarginated (Figs. 6a–6c). Lateral lobes slender, with a strong tooth at ventral base (Fig. 8b); ringed part elbowed in the widest portion, converging; basal piece well-developed and bifurcated (Fig. 8c). Median lobe strongly curved, shorter than tegmen, dorsal plate shorter than ventral plate, apex of ventral plate emarginated (Fig. 9a). Median foramen not elongated. Endophallus with one band of supporting armature, 4 basal plate-like sclerites, and 3 rod-like sclerites. Ejaculatory duct single. Female terminalia: Setae of sternite VIII dense and long. Spermathecal capsule and gland positioned on apex of spermathecal duct. Spermathecal capsule strongly sclerotized, composed of an apical orb and a long stalk, spiculum ventrale longer than abdomen. Etymology. The generic name is a combination of a Greek word tsounkrána (τσουγκράνα) and the genus name Glenea. The Greek word “tsounkrána” refers to the shape of sternite VII in male, which looks like a rake. Gender feminine. Distribution. Malaysia. Remarks. It is very similar to Glenea (Breuning, 1956; Breuning, 1958) by the elytral lateral carinae and truncated elytral apex, and the following characters are quite common in Glenea members: endophallus with 4 basal plate-like sclerites (Lin et al., 2009; Lin, Tavakilian et al., 2009a,b; Lin & Lin, 2011; Lin & Yang, 2011a, b; Lin et al., 2018), and 3 rod-like sclerites (Lin et al., 2009; Lin, Tavakilian et al., 2009a,b; Lin & Lin, 2011; Lin & Yang, 2011a, b; Lin & Dai, 2012; Lin, 2013); spermathecal capsule strongly sclerotized, composed of an apical orb and a long stalk (Lin et al., 2009; Lin, Tavakilian et al., 2009b; Lin & Yang, 2011a, b; Lin & Dai, 2012). We separate it from Glenea based on the following reasons.: 1) Glenea is heterogeneous (Lin, Montreuil et al., 2009;), even though outer characters are very similar (Lin & Tavakilian, 2012), this peculiar species does not match with any type species of the subgenera; 2) Though most of characters can be found in the previous Glenea members, and the peculiar male sternite might not be suitable for generic level, but with only one band of supporting armature and the emarginated apex of the ventral plate of the median lobe, this convinced the authors to make a new genus. Most members of Saperdini have zero or two bands of supporting armature, rounded to the pointed apex of the ventral plate of the median lobe (Lin et al., 2009; Lin, Tavakilian et al., 2009a, b; Lin & Yang, 2011a, b; Lin & Dai, 2012; Lin, 2013; Lin et al., 2018). 3) Although the sexual dimorphism (on pubescence markings) referred to the subgenus Glenea (Acutoglenea) Breuning, 1958, and the dark integument referred especially to G. (A.) versuta basaloides Breuning 1958, G. (A.) versuta maura Pascoe, 1867, it can not be included in the subgenus Acutoglenea because of the non-simple male claws and very different male terminalia (based on the first author’s unpublished data). Besides, the type species Glenea (Acutoglenea) acuta (Fabricius, 1801) has a stouter female, with elytral length less than twice basal width, fourth antennomere much shorter than scape, which are very different from the new taxon herein described. 4) We have checked the subgenus Glenea (Lineatoglenea) Breuning, 1950, which is represented by a unique type species Glenea (Lineatoglenea) lineatopunctata Breuning, 1950 from Malaysian Borneo. There are no images available, and we did not have an opportunity to examine the type specimen which should be deposited in University of Malaysia, Sarawak (Breuning, 1950a). Based on the original description, it shares with the new taxon by antennae longer than body, similar antennomere ratio, pronotum and elytra, however it differs from the new taxon by the fifth male abdominal segment provided at the end with a short median longitudinal ridge. 5) We have checked the subgenus Glenea (Spiniglenea) Breuning, 1958, which is represented by a unique type species Glenea (Spiniglenea) spinosipennis Breuning, 1958 from Malaysian Borneo. It also has no images available, and we did not have an opportunity to examine the type specimen which should be deposited in University of Malaysia, Sarawak (Breuning, 1958b). Based on the original description, it is difficult to separated it from the new taxon on genus level, since it was based only on a female. However, it is surely not the same species. 6) We compared the new taxon with Glenea (Metaglenea) Breuning, 1956, which is represented by a species from Sumatra, and Glenea (Porphyrioglenea) Breuning, 1956, which is represented by a species from West Malaysia and Sabah, East Malaysia. They can be easily distinguished from the new taxon by the very close antennal tubercles, shorter and stouter antennae. Glenea (Pseudotanylecta) Breuning, 1956, Glenea (Subgrossoglenea) Breuning, 1956, Glenea (Tanylecta) Pascoe, 1866 also from Malaysia and Indonesia, can be separated by the close and protruding antennal tubercles. 7) Glenea (Poeciloglenea) Aurivillius, 1920, Glenea (Punctoglenea) Breuning, 1956, Glenea (Reginoglenea) Breuning, 1956, Glenea (Rubroglenea) Breuning, 1956, Glenea (Rufoglenea) Breuning, 1956, Glenea (Stiroglenea) Aurivillius, 1920, Glenea (Vanikoroglenea) Breuning, 1956, Glenea (Vittiglenea) Breuning, 1956, Glenea (Volumnia) Thomson, 1860 and all other subgenera have been studied by the first author, and none of them are suitable for the new taxon. 8) The new taxon differs from Glenea (Lobunguiglenea) Lin & Tavakilian, 2014 by the male claws with only anterior claw of mesotarsus appendiculate with small lobe in inner side, instead of all claws appenciculated in outer sides, and genitalia with median lobe strongly curved, apex of ventral plate emarginated, instead of genitalia with median lobe slightly curved, apex of ventral plate pointed.Published as part of Lin, Mei-Ying & Ge, Si-Qin, 2021, Tsounkranaglenea hefferni gen. et sp. nov. from Sabah, Malaysia (Coleoptera Cerambycidae, Lamiinae: Saperdini), pp. 289-297 in Zootaxa 5048 (2) on page 290, DOI: 10.11646/zootaxa.5048.2.9, http://zenodo.org/record/555211

Fabrication and characterisation of novel Ge MOSFETs
No full textAs high-k dielectrics are introduced into commercial Si CMOS (Complimentary Metal Oxide Semiconductor) microelectronics, the 40 year channel/dielectric partnership of Si/SiO2 is ended and the door opened for silicon to be replaced as the active channel material in MOSFETs (Metal Oxide Semiconductor Field Effect Transistor). Germanium is a good candidate as it has higher bulk carrier mobilities than silicon. In addition, Si and Ge form a thermodynamically stable SiGe alloy of any composition, allowing Ge to be implemented as a thin layer on the surface of a standard Si substrate. This thesis is a practical investigation on several aspects of Ge CMOS technology.
High-k dielectric Ge p-MOSFETs are electrically characterised. A large variation in interface state densities is demonstrated to be responsible for a threshold voltage shift and this is proportional to reciprocal peak mobility due to the Coulomb scattering of carriers by charged states. A theoretical mobility is fitted to that measured at 4.2 K and confirms that interface states are the main source of interface charged impurities.
The model demonstrates a reduction in the interface charged impurity density in p-MOSFETs that underwent a PMA (Post Metallisation Anneal) in hydrogen atmosphere and that the anneal also reduces the RMS (Root Mean Square) dielectric/semiconductor interface roughness, from an average of 0.60 nm to 0.48 nm.
High-k strained Ge p-MOSFETs are electrically characterised and have peak mobilities at 300 K (470 cm2 V-1 s-1) and 4.2 K (1780 cm2 V-1 s-1) far in excess of those measured for the unstrained Ge p-MOSFETs (285 cm2 V-1 s-1,785 cm2 V-1 s-1 respectively). Strained Ge n-MOSFETs perform significantly worse than standard Si P, - MOSFETs primarily due to a high source/drain resistance.
A 10 nm thick SiGe-01 (On Insulator) layer with a Ge composition of 58% is obtained from a 55 nm Si0_88Ge1o2. initial layer on 100 nm Si-Ol substrate via the germanium condensation technique. For the first time, germanium is demonstrated to diffuse through the BOX (Buried OXide) during Ge-condensation and into the underlying Si substrate. An order of magnitude increase in the calculated ITOX (Internal Thermal OXidation) rate of the BOX in the final stages of Ge-condensation is hypothesised to be responsible for stopping this diffusion

In chapter Two, I discuss the study of characters of Lin Ze-Xu, also makes a deep analysis of author\u27s purpose of writing him. In chapter Three, I analyze supporting actors and actress. Meanwhile, I illustrate author\u27s purpose of writing supporting actress because the author had different manner to describe supporting actress. Moving to the Chapter Four, I mainly focus on the plots of Judge Lin, and organize cases of Lin Ze-Xu and his subordinates to understand features of cases. In Chapter Five, I represent the causes of Opium War. China and England had difference of opinions of opium. Therefore, it is easier to comprehend what the author\u27s purpose is. In the last chapter I summarize the main points of the preceding chapters and confirm particularity of Judge Lin
High quality Schottky contacts for limiting leakage currents in Ge-based Schottky barrier MOSFETs
No full textSchottky barrier (SB) Ge channel MOSFETs suffer from high drain-body leakage at the required elevated substrate doping concentrations to suppress source-drain leakage. Here we show that electrodeposited Ni-Ge and NiGe/Ge Schottky diodes on highly doped Ge show low off current, which might make them suitable for SB p-MOSFETs. The Schottky diodes showed rectification of up to 5 orders in magnitude. At low forward biases the overlap of the forward current density curves for the as deposited Ni/n-Ge and NiGe/n-Ge Schottky diodes indicates Fermi-level pinning in the Ge band gap. The SB height for electrons remains virtually constant at 0.52 eV (indicating a hole barrier height of 0.14 eV) under various annealing temperatures. The series resistance decreases with increasing annealing temperature in agreement with four point probe measurements indicating the lower specific resistance of NiGe as compared to Ni, which is crucial for high drive current in SB p-MOSFETs. We show by numerical simulation that by incorporating such high quality Schottky diodes in the source/drain of a Ge channel PMOS, highly doped substrate could be used to minimize the subthreshold source to drain leakage current
Electrodeposited Ni/Ge and germanide schottky barriers for nanoelectronics applications
No full textIn recent years metal/semiconductor Schottky barriers have found numerous applications in nanoelectronics. The work presented in this thesis focuses on the improvement of a few of the relevant devices using electrodeposition of metal on Ge for Schottky barrier fabrication. This low energy metallisation technique offers numerous advantages over the physical vapour deposition techniques. Electrical characteristics of the grown diodes show a high quality rectifying behaviour with extremely low leakage currents even on highly doped Ge. A non-Arrhenius behaviour of the temperature dependence is observed for the grown Ni/Ge diodes on lowly doped Ge that is explained by a spatial variation of the barrier heights. The inhomogeneity of the barrier hights is explained in line with an intrinsic surface states model for Ge. The understanding of the intrinsic surface states will help to create ohmic contacts for doped n-MOSFETs. NiGe were formed single phase by annealing. Results reveal that by using these high-quality germanide Schottky barriers as the source/drain, the subthreshold leakage currents of a Schottky barrier MOSFET could be minimised, in particular, due to the very low drain/body junction leakage current exhibited by the electrodeposited diodes. The Ni/Ge diodes on highly doped Ge show negative differential conductance at low temperature. This effect is attributed to the intervalley electron transfer in Ge conduction band to a low mobility valley. The results show experimentally that Schottky junctions could be used for hot electron injection in transferred-electron devices. A vertical Co/Ni/Si structure has been fabricated for spin injection and detection in Si. It is shown that the system functions electrically well although no magnetoresistance indicative of spin injection was observed
Notes on the Determiner Ge and Related Problems
No full text[[abstract]]This work presents some reflections on the determiner ge ‘each, numerous’ in Mandarin Chinese, focusing on its quantificational properties and related questions. T.-H. Lin (1998, 2004) examines the syntactic and semantic properties of ge; also see Kung 1993 and Soh 1998). But these works only discuss the adverbial use of ge, not its determiner use.[[fileno]]204_JA07_2005_v1_p267[[department]]語言學研究
