Abstract:

Semiconductor nanocrystals are expected to play an important role in the development of new generation of microelectronic and photonic devices such as light emitting diodes and memory elements. Optimization of these devices requires detailed investigations. Various spectroscopic techniques have been developed for material and devices characterization. This study covers the applications of the following techniques for the analysis of nanocrystalline materials: Fourier Transform Infrared Spectroscopy (FTIR), Raman Spectroscopy, X-Ray Diffraction (XRD) and X-Ray Photoelectron (XPS).

Abstract:

Since last few years, many artificial and modified gemstones are available whose origins are questionable and even an experienced gemmology expert may be unable to differentiate between these artificial gemstones. Raman spectroscopy is considered to be an effective method to differentiate natural and artificial gemstones as it involves a very simple sample preparation, is non-destructive in nature, and is sensitive, precise, and accurate. In the present study, Raman spectroscopy was employed to identify different gemstones available in the mineralogical collection at the Department of Earth Sc

Abstract:

Raman microspectroscopy is a non-destructive, label-free technique that offers information-rich molecular analysis of living cells. This work is the first reported Raman spectroscopic study of human induced pluripotent cells (hiPSCs), a very promising new source of non-embryonic pluripotent stem cells for drug screening, toxicity assessment, regenerative therapies, and clinical research. The Raman signatures of hiPSCs and human embryonic stem cells (hESCs) were found to be highly similar, and both distinguishable from differentiated hESCs in terms of relative Raman peak intensities and varianc

Abstract:

In many geologic environments, dominant1y aqueous solutions contain low concentrations of CO2. At ambient temperature, in fluid inclusions which trap these solutions, the typical phase assemblage consists of a CO2-rich vapor (where Pco2 = PintemaI) and an aqueous phase containing dissolved salts and CO2. In this study, the CO2 minimum detection limits (MDLs) using microthermometry and laser Raman spectroscopy are established in terms of Pco2 using synthetic H20-C02 inclusions. The purpose of the microthermometric experiments was to examine the diagnostic CO2 phase changes and determine the qua

Abstract:

Nitride-based semiconductor materials make it possible to fabricate optoelectronic devices that operate in the whole electromagnetic range, since the band gaps of these compounds can be modified by doping. Among these materials, the sp2-hybridized boron nitride has properties that make it a potential candidate for integration in devices operating in the short-wavelength limit, under harsh environment conditions, due to the strength of the B-N bond. Nevertheless, this binary compound has been the less studied material among the nitrides, due to the lack of complete control on the growth proces

Abstract:

Spectroscopic characterization of ferric soybean peroxidase with peroxides were studied to determine the ligand coordination and to characterize the structure of the heme active site and its intermediates (ferryl species). The lifetime, chemical reactivity and distinctive colors of the ferryl species (FeIV) formed during the oxidation of peroxidase (FeIII) by peroxides enabled structure, dynamics and reaction mechanisms to be studied. Resonance Raman spectroscopy was used as a means of characterizing the structure of the soybean peroxidase and its intermediates. Excitation in the Soret absorp

Abstract:

In the last two decades solid-state nanopores have been widely investigated for the development of efficient and functional sensing platforms that enable real-time identification of biomolecules and even sequencing. Besides the typical electrical readout, single solid-state nanopores have been integrated with plasmonic nanostructures to add additional sensing modalities by using optical techniques such as Surface-enhanced Raman Spectroscopy (SERS). However, these nanosensors often exhibit low throughput which limits their use for real biological applications. Here, a large area and low-cost ap

Abstract:

This dissertation will have three chapters. In chapter one, a comprehensive review on defects in two dimensional materials will be presented. The aim of this review is to elaborate on different types of defects in two dimensional (2D) materials like graphene and transition metal dichalcogenides (TMDs). First, different types of point and line defects, e.g. vacancies, anti-sites, guest elements, adatoms, vacancy clusters, grain boundaries, and edges, in these materials are categorized in terms of structure. Second, interactions among defects are discussed in terms of their rearrangement for low

Abstract:

La première partie de cette thèse est consacrée à l'étude par spectroscopie Raman de nanofils de silicium isolés fabriqués par CVD. L'analyse des spectres Raman indique la présence à la fois des phases du silicium cristallin (cSi) -520 cm-l et amorphe (aSi) - 470 cm-l qui forment une structure cœur-coquille (cSi-aSi). La température de Tcsi < Tasi est déterminée en fonction du rapport des intensités Stokes/anti-Stokes, de la position et de la largeur à mi-hauteur des pics Raman, On montre que le cœur des nanofils est en bon contact thermique avec le substrat, favorisant l'évacuation de chal
