Multiple solutions for coercive p-Laplacian equations
No full textAbstractWe obtain multiple nonzero solutions for coercive p-Laplacian equations. In order to obtain the third nonzero solution, we use the second deformation lemma to construct the desired mountain pass path
RoMEO Studies 5: IPR issues for OAI Data and Service Providers
No full textThis paper is the fifth in a series of studies emanating from the UK JISC-funded RoMEO Project (Rights Metadata for Open-archiving). It reports the results of two surveys of OAI Data Providers (DPs) and Service Providers (SPs) with regards to the rights issues they face. It finds that very few DPs have rights agreements with depositing authors and that there is no standard approach to the creation of rights metadata. The paper considers the rights protection afforded individual and collections of metadata records under UK Law and contrasts this with DP and SP’s views on the rights status of metadata and how they wish to protect it. The majority of DP and SPs believe that a standard way of describing both the rights status of documents and of metadata would be usefu
Thermodynamic assessments of the Er-Sb and Sb-Tm systems
No full text通讯作者：E-mail address: [email protected] (X.J. Liu).By using the calculation of phase diagrams (CALPHAD) method, thermodynamic assessments of the Er-Sb and Sb-Tm systems were carried out based on the available experimental data including thermodynamic properties and phase equilibria. The Gibbs free energies of the liquid, hcp, and rhombohedral phases in the Er-Sb and Sb-Tm systems were modeled by the substitutional solution model with the Redlich-Kister formula, and the intermetallic compounds (Er(5)Sb(3), alpha ErSb, beta ErSb, ErSb(2), Sb(2)Tm, alpha SbTm, beta SbTrn, alpha Sb(3)Tm(5), and beta Sb(3)Tm(5) phases) in these two binary systems were described by the sublattice model. An agreement between the present calculated results and experimental data was obtained.National Natural Science Foundation of China

Study on the oxygen concentration reduction in heavily Sb-doped silicon
No full textIt was determined that oxygen concentration in heavily Sb-doped silicon was about 40% lower than that in the lightly doped Czochralski grown silicon and decreased with increasing content of Sb by means of coincident elastic recoil detection analysis. Through thermodynamic calculation, the oxygen loss by evaporation from the free surface of melt is only due to the formation of SiO, and Sb2O3 evaporation can be neglected. The basic reason for oxygen concentration reduction in heavily Sb-doped CZSi was that oxygen solubility decreased when element Sb with larger radius doped degenerately into silicon crystal.

Laser processing of solution based antimony doped tin oxide thin films
No full textAntimony doped Tin oxide (SnO2:Sb, or ATO) is of interest as an alternative to Indium Tin Oxide (ITO) for large area optoelectronic applications. There is a particular interest in the potential for solution based coatings based on nanoparticulate suspensions of SnO2:Sb. However, solution processed films typically require a high temperature (~700⁰C) annealing step to achieve the desired electrical and optical properties. This is disadvantageous for applications that would benefit from low cost, low temperature/flexible substrates. As an alternative to conventional high temperature annealing, excimer laser processing can provide highly localized energy dissipation, and is an attractive technique to functionalise coated materials. Therefore the work presented in this thesis investigates the use of excimer laser processing to optimise the electrical and optical properties of solution deposited SnO2:Sb thin films for use in electroluminescent display devices. Thin films of SnO2:Sb were deposited using dip coating, inkjet printing and the spin coating technique. By varying the numbers of spin coatings deposited, a series of samples were prepared on Eagle XG glass substrates with different thicknesses of SnO2:Sb (ranging from 0.2 μm to 1.4 μm). The initial sheet resistance, optical transmission and crystal structure of the deposited films was studied. The films were subsequently post processed using three different annealing techniques: (i) Laser Processing: samples were laser processed in air to optimise the sheet resistance and optical transmission
Study on the effect of mechanical alloying on properties of Zn-Sb alloy
No full textThe effect of mechanical alloying on Zn-Sb alloy system is investigated with X-ray diffraction (XRD), laser grain size analysis and differential scanning calorimetry (DSC) respectively. The results of laser particle size analysis shows that the particle size decreases with increasing of the grinding time between 0 and 24 h. XRD and DSC results indicate that longer the grinding time of Zn-Sb is, the more content of Zn(4)Sb(3) become in the product in this process
Alloying Sb into all inorganic lead-free CsBi3I10 for improving the crystal growth and photovoltaic performance
No full textThe all-inorganic lead-free perovskite CsBi3I10 has recently emerged as a promising light absorber. However, the poor morphology of CsBi3I10 film remains a critical issue for fabricating high-performance solar cells. In this work, we report an ion substitution strategy by alloying Sb into CsBi3I10, resulting in dramatically improved grain crystallinity and markedly reduced bandgaps for better light utilization. The Sb-substituted CsBi3I10 film composed of highly-crystalline large grains can form a bulk-heterojunction structure with the electron acceptor PCBM to facilitate the exciton separation. With PTAA as the hole transport layer, the solar cell assembled using Cs(Bi0.7Sb0.3)3I10 can afford a champion power conversion efficiency of 1.54% with a high Voc of 0.81 V.No Full Tex
