Low Energy Electronic Raman Scattering in Cuprate High Temperature Superconductors
… behavior. A magnetic field is observed to affect Raman spectra in way similar to the way temperature does. Nevertheless, the peak intensity change as a function of magnetic field is different from that of temperature. The upper critical fields were extracted by analyzing the field dependence of …

Complex phase behavior of exotic oxides: optical spectroscopy studies
… have used two optical spectroscopy techniques, Raman scattering spectroscopy and spectroscopic ellipsometry, to study complex phase transition behavior exhibited by the doped rare-earth manganese oxides, R1_xDxMn03 (0 :::; x :::; 1), and the layered calcium ruthenium oxide, Ca3Ru20 7 , in which …

Raman spectroscopy of metallic carbon nanotubes
… that are both technologically promising for electronic applications, and scientifically interesting for studying the physics of low dimensional materials. In this thesis, we present a detailed study of the inelastic light scattering (Raman) spectrum of individual metallic carbon nanotubes, …

Photothermal properties and applications of gold nanorods
… layer thicknesses are measured by dynamic light scattering (DLS). The cooling dynamics of GNRs are best measured by tuning the pump-probe laser wavelength to the absorption peak of the sample solutions. The heat capacity and thermal conductivity were calculated numerically based on a cylindrical …

Interlayer optical response of yttrium barium (copper (cobalt, zinc)) oxide
… regulating interlayer hopping. We find that the electronic component of the c-axis optical conductivity in $\rm YBa\sb2Cu\sb3O\sb{6 + x}$ is roughly constant below 800 cm$\sp{-1}$, and is well fit over the frequency range 800 cm$\rm\sp{-1} \le\omega\le3200\ cm\sp{-1}$ by $\sigma\sb{\rm …

Bio-interfaced Nanolaminate Surface-enhanced Raman Spectroscopy Substrates
Surface-enhanced Raman spectroscopy (SERS) is a powerful analytical technique that combines molecular specificity of vibrational fingerprints offered by Raman spectroscopy with single-molecule detection sensitivity from plasmonic hotspots of noble metal nanostructures. Label-free SERS has attracted …
