Inelastic light scattering studies of quantum phase transitions in CuxTiSe2 and multiferroic TbMnO3
Abstract In this dissertation, inelastic (Raman) light scattering techniques are used to probe the temperature- and magnetic-field-induced phase transitions of two strongly correlated systems – the magnetoelectric multiferroic TbMnO3 and the layered dichalcogenide TiSe2 . In general, strongly …

Inelastic Light Scattering Studies of Quantum Phase Transitions in Copper Titanium Diselenium and Multiferroic Terbium Manganese Trioxygen
The second focus of this dissertation is the study of quantum phase transitions in TiSe2 as a function of temperature and Cu-intercalation, and the comparison of the effects of intercalation and pressure on the charge-density-wave (CDW) order in this system. All these parameters---temperature, …

Magnetic-field- and pressure-tuned phases in LaxPryCa1−x−yMnO3 and Mn3O4: inelastic light scattering studies and single crystal growth
… spinel Mn3O4. For this study, Raman (inelastic light) scattering spectroscopy was used as a main experimental technique because Raman scattering can provide detailed information—such as energy, symmetry, and lifetime information—about all the important electronic, magnetic, and lattice …

Resonant Raman scattering studies of III-V semiconductor microstructures
Raman spectroscopy, an inelastic light scattering technique, explores III-V semiconductors by conveying crystal lattice structural information and by probing carrier dynamics both directly and via the electron-phonon interaction. We have examined three physical systems accentuating three aspects of …

Time-resolved Raman scattering in GaAs multiple quantum well structures
… the application of the conventional Raman scattering technique was extended to the picosecond time domain. Inelastic light scattering from the elementary intersubband excitations of an electron-hole plasma reveals both the absolute carrier density and the occupancy of the electronic …

Raman scattering in mixed crystal semiconductors
… the effects of substitutional disorder on the inelastic light scattering by phonons in three semiconductor alloys; (GaSbh-x(Ge2)x, GaAsxSbl-x' and AlxGal-xAs. We measure the asymmetric broadening and shifting of the longitudinal optic (LO) phonon lines as a function of disorder and observe …

Raman scattering in heavy rare earth metals
Inelastic light scattering spectra were measured in MBE grown single crystal films of Dysprosium, Erbium and yttrium. In order to measure the weak Raman signals of metals a single grating monochromator was designed and constructed and added to an existing double grating monochromator to improve the …

Light Scattering Spectroscopy of Tissue Phantoms for Applications in Biomedical Sciences
Inelastic light scattering reveals information on an analyte through interactions of atoms or molecules with photons. Micro-mechanical properties of samples are probed with Brillouin microscopy, through interactions of light with acoustic phonons (sound waves), and their chemical information is …

Raman spectroscopy of metallic carbon nanotubes
… this thesis, we present a detailed study of the inelastic light scattering (Raman) spectrum of individual metallic carbon nanotubes, with a focus on the influence of electronic excitations and charged carriers. We have demonstrated that the frequency and linewidth of certain phonon modes of …

Raman scattering studies of spinels CoV2O4 and MnV2O4
In this thesis, I present Raman scattering studies of the strongly correlated spinels CoV2O4 and MnV2O4. In CoV2O4, exclusive attention is given to a triply degenerate (T2g) phonon in order to determine the material's structural properties and explore coupling between the lattice and other degrees …
