Art, Biography, Sexuality: Patrick Procktor and Keith Vaughan
No full textThis critical review forms a reflection on the research published within the following publications:
Patrick Procktor: Art and Life (Unicorn Press, 2010)
Keith Vaughan: The Mature Oils 1946-1977, (Sansom & Co., 2012)
The research is on two artists, Patrick Procktor (1936-2003), and Keith Vaughan (1912-1977). The monograph on Procktor – previously one of the least documented of the generation of artists who came to prominence in London in the Sixties – positions him in a history of art from which he had been notably absent. The research on Vaughan asserts a new reading of his work, one that is both deeper and more nuanced in its analysis of the ways in which personal experience and sexuality are encoded autobiographically within his work. Crucially, in both artists biography and work are symbiotically linked; the research therefore examines the links between life and art.
Revisionary in intent, the work examines trajectories of experience of gay British (or rather, English) artists in the twentieth century, artists who sought to express themselves and forge careers within the constraints of a heteronormative society, albeit one in which attitudes to sexuality were undergoing change. As gay men, both were constrained by the social mores of their times, and each used painting as a means to affirm personal and sexual identities. A key research interest is in the ways in which sexuality and persona are reflected in critical responses to the artist’s work: in Vaughan, Procktor and other gay male artists of the period. The writing on both Procktor and Vaughan examines the relationship between their personal and professional/artistic lives, framed within a broader socio-political and art historical context. It asserts the place of biography as a means to understand and form new readings of the work. The work adds substantially to the literature and wider discourse on post-war British painting and social history
Patrick Chamoiseau Recovering Memory
No full textThis timely new book skillfully examines the work of the award-winning writer Patrick Chamoiseau. Considered by many as one of the most innovative writers to hit the French literary scene in over 40 years, Chamoiseau made his name with his book Texaco (published in 1992 and winner of the highest literary prize in France, the Prix Goncourt). His books have gone on to sell millions and his work has been translated by a number of academic presses. McCusker sets the author in context, providing a valuable contribution to 'memory studies' by looking at literary representation of memory in Martinique, a society founded on slavery but now politically assimilated to the metropolitan centre, France.Title Page -- Contents -- Introduction -- 1: Beginnings: The Enigma of Origin -- 2: 'Une tracée de survie': Autobiographical Memory -- 3: Memory Re-collected: Witnesses and Words -- 4: Memory Materialized: Traces of the Past -- 5: Flesh Made Word: Traumatic Memory in Biblique des derniers gestes -- Afterword -- Notes -- Bibliography -- IndexThis timely new book skillfully examines the work of the award-winning writer Patrick Chamoiseau.

Development of a prototype photoacoustic microscope and spectroscope and advanced semiconductor material characterization
No full textThe thesis can be divided into two parts.
In the first part of my thesis, I present the design, construction and test results of a prototype gas-cell Photoacoustic (PA) Spectrometer and Microscope. It is a low
cost, non-contact technique, which can be used to characterize semiconductor band-gap structures and subsurface defects. It requires no liquid coupling and no
sample surface preparation in advance.
The instrument development includes the optical system design, mechanical design of the PA cell using AutoCAD®, pre-amplifier circuit design, system noise analysis, hardware control, data acquisition system and graphical user interface (GUI) development using LabView®. A multiple-microphone detection scheme, helium gas coupling, acoustic resonance and a high power laser light source are
used to enhance the PA signal and to increase the data acquisition speed. The PA system is calibrated to remove the acoustic resonance effect and the background
fingerprint of light source intensity spectrum. The linear relationship between the PA signal and the source intensity is verified. The impacts of the lock-in amplifier
performance, the focus offset and the coupling gas within the cell on the PA signal are discussed.
Various samples are used to verify performance of the developed PA system. These include Silicon wafers, GaAs wafers, multi-layered structures on silicon substrates, carbon-black powder, laser-machined air trenches, bonded silicon wafers and a packaged IC chip. For spectroscopy applications, the PA spectra of two types of GaAs wafers are characterized successfully. For microscopy applications, the PA system is proven to have a vertical resolution of ~ 20 nm and a lateral resolution of ~ sub-100 um. Its probe depth could be as deep as 450 um below the silicon surface. The data acquisition speed of the PA system is improved for industrial applications. Two high-resolution (10,000 pixels) thermal images (one in phase and another in amplitude) of semiconductor devices can be obtained in less than 50 seconds across an area of approx. 9 mm x 9 mm.
In the second part of my thesis, other related non-destructive characterization work on advanced semiconductor materials is presented. In chapter six, Synchrotron X-ray Topography (SXRT) and Micro-Raman Spectroscopy (uRS) are used to study two sets of the femto-second and nano-second laser machined grooves on InP substrates. In chapter seven, other characterization work is presented to study the H2 preconditioning effect on self-assembled Ge-islands on Silicon. Both cases demonstrate the commercialised metrology tools’ capabilies to analyse the distribution profile of the strain and the chemical composition on the top surface. The PA system prototype presented in this thesis can be used as a complementary tool. It provides ultra-deep probe depth for the subsurface defects, when compared to the SXRT and the uRS methods
Heating stage spectroscopy: infrared, raman, energy dispersive x-ray and x-ray photoelectron spectroscopy
No full textSpectroscopy and especially infrared spectroscopy has been a widely used technique in the industry for the structural and compositional analysis of organic, organometallic, metalorganic, inorganic and polymeric materials in addition to quality control of raw materials and commercial products. In general, one can say that spectroscopic techniques are concerned with the interaction between radiation of some sort and matter, using radiation with an energy or wavelength appropriate to the distance and time scales relevant to the microscopic study of atoms, molecules and solids. In this regard a large number of radiation types can be used including:\ud

Streaking and splashing: design of a grazing incidence x-ray streak camera and time-resolved measurements of the structure of water
No full textThe performance of cesium iodide photocathodes has been characterized for use with grazing incidence soft x-rays. The total electron yield and pulsed quantum efficiency has been measured in a reflection geometry as a function of photon energy (100 eV to 1 keV), angle of incidence, and the electric field between the anode and photocathode. The total electron yield and pulsed quantum efficiency increase as the x-ray penetration depth approaches the secondary electron escape depth Unit quantum efficiency in a grazing incidence geometry is demonstrated. A weak electnc-field dependence is observed for the total yield measurements, while no significant dependence is found for the pulsed quantum efficiency. The effect of the pulse height distribution on the detective quantum efficiency is discussed Theoretical predictions agree accurately with expenment.
Demonstrated unit quantum efficiency in a reflection geometry motivated the development of a grazing incidence x-ray streak camera for the Ultrafast X-ray Science beamline, under construction at the Advanced Light Source, Lawrence Berkeley National Laboratory, USA Design considerations particular to synchrotron radiation sources are discussed. An analytical model and particle simulation for a camera incorporating magnetostatic imaging and meander sweep plates is presented. The camera is characterised with the third harmonic from a titanium-sapphire based laser system, 70 ps intrinsic and 150 fs “sliced” x-ray photon pulses from a synchrotron bend magnet source. A grazing incidence x-ray streak camera with an instrument temporal response of 6 ps is demonstrated.
Dynamical changes in the structure factor of liquid water are measured using time-resolved x-ray diffraction techniques with 100 ps resolution. On short time scales, before the system has had time to expand following femtosecond optical excitation, temperatureinduced changes associated with rearrangements of the hydrogen-bonded structure at constant volume are observed. Transient changes in the pair correlation function associated with isochonc heating effects are extracted and interpreted in terms of a decrease in the local tetrahedral ordering in the liquid

The investigation in "Dora Bruder" of Patrick Modiano
No full textreservedIl presente lavoro si propone di affrontare il tema dell’indagine, dell’inchiesta investigativa nel romanzo “Dora Bruder” dello scrittore francese Patrick Modiano, pubblicato nel 1997. Si tratta del più noto successo editoriale dell’autore, il quale, in una narrazione al contempo biografica ed autobiografica, si mette sulle tracce di Dora Bruder, una giovane ragazza ebrea scomparsa nel 1941, di cui si sono perse definitivamente le tracce. La presente tesi si compone di tre capitoli. Nel primo, si analizzeranno i motivi che spingono l’autore ad occuparsi della vicenda della giovane ragazza scomparsa proprio durante la seconda guerra mondiale. Successivamente, nel secondo capitolo, si passerà ad affrontare come l’autore compie la propria indagine per comprendere che cosa le sia accaduto, diventando una sorta di investigatore su un vecchio caso di scomparsa. Ed infine, nell’ultimo capitolo, si analizzerà quale sarà l’esito della sua indagine.This work proposes to deal with the subject of investigation in the novel "Dora Bruder" by French writer Patrick Modiano, published in 1997. It’s the most known publishing success of the author, which, in a narrative in the meantime biographical and autobiographical, goes on the trail of Dora Bruder, a young Jewish girl disappeared in 1941, of whom all traces have been definitively lost. This thesis is composed by three chapters. In the first, we will analyse the reasons why the author deal with the story of the young girl vanished during the Second World War. Then, in the second chapter, we will approach how the author does his own investigation to understand what happened to her, becoming sort of a detective on an old case of disappearence. Finally, in the last chapter, we focus on which it’ll be the outcome of his investigation
Investigations of ultra shallow junction ion implanted biaxial tensile strained silicon by means of X-Ray, Raman and photoacoustic techniques
No full textThe application of strain to the active channel region of the metal-oxide-semiconductor-field-effect-transistor (MOSFET) has become a necessary practice in integrated circuit (IC) fabrication. The introduction of strain allows increased carrier mobilities, and concomitant device performance enhancements, which are independent of MOSFET scaling. Biaxial tensile strained silicon ("-Si), resulting from epitaxial growth of silicon on a Si1!xGex virtual substrate gives rise to enhanced electron mobilities and, for certain dopants, increased electrical activation. For these reasons it is the material of interest in this thesis.
The prospects for industrial implementations of "-Si are heavily dependent on the effects of device processing steps, and the controllability of defect and dopant profiles. Of special interest to the current work is the suitability of "-Si subjected to low energy antimony implants and low thermal budget rapid thermal anneal (RTA), for the production of ultrashallow, abrupt junctions, appropriate for future generation source-drain extensions (SDE).
Examined in the wider project are the effects of strain on dopant activation and diffusion through Differential Hall and SIMS measurements carried out by project partners. These
measurements provide context for the work herein and demonstrate the desirability of "-Si as a n-MOSFET channel material.
For our part, the effects of implant and anneal processes are investigated through both high resolution x-ray diffraction and micro-Raman (µ-Raman) spectroscopy. Synchrotron x-ray topography is used to identify the strain relaxation processes in both the "-Si epilayer and
the Si1!xGex virtual substrate. Data obtained during the project called into question the validity of traditional µ-Raman interpretations in the context of degenerately doped silicon, under these conditions additional theoretical considerations are necessary. The µ-Raman data presented herein demonstrates sensitivities to both implant damage and to dopant activation and these dependencies are
theoretically accouncted for.
Finally, Photoacoustic Spectroscopy is shown to be a technique capable of non-destructive detection of ion implant damage within the top ⇠10 nm of the silicon. These uniquely sensitive measurements araise due to the particular experimental set up used which invoke
a strong dependence on the thermal interface resistance within the sample
