High pressure surface enhanced Raman scattering spectroscopy
Surface-enhanced Raman scattering spectroscopy (SERS) was combined with the diamond anvil cell technique to study molecular monolayers and single molecules under high pressure. Vibrational spectra up to 8 GPa were obtained for self-assembled monolayers (SAMs) of the energetic material simulant …

Low-energy electron diffraction effects at complex interfaces
Low-energy electron scattering was used as a tool to study electron-stimulated processes at complex interfaces. The electron diffraction in each complex interface is theoretically treated by a multiple scattering formalism for quantitative analysis. Mathematical descriptions of electron-stimulated …

New technologies for spectroscopy of materials under static and shock compression
… by the novel combination of surface-enhanced Raman scattering spectroscopy with diamond anvil cell technology. The samples used were benzenethiol (BT) and benzene methane thiol (BMT) adsorbed onto photonic substrates composed of silver films over polystyrene nanospheres. Results indicated that …

Electrodeposited macroporous vanadium oxide Li-ion battery materials
… under lithiation using X-ray diffraction, Raman scattering and electron microscopy. The data show that electrodes with nanoscale dimensions and macroscale porosity are fundamentally limited for high-rate performance if the intrinsic electronic conductivity is poor, even when fully soaked …

From fano to nano: mechanisms and applications of surface enhanced raman spectroscopy
Surface enhanced Raman scattering/spectroscopy (SERS) is a trace sensing technique that uses collective surface electron oscillation-light excitations (plasmon-polaritons) to enhance the inelastically scattered light (Raman scattering) from a material of choice. However, SERS studies suffer from a …

Magnetic-field- and pressure-tuned phases in LaxPryCa1−x−yMnO3 and Mn3O4: inelastic light scattering studies and single crystal growth
… manganese-based 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 …

Complex phase behavior of exotic oxides: optical spectroscopy studies
"We 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 …

Probing the Ultrafast Dynamics of Higher-Lying Excited States of Molecular Switches with Femtosecond Stimulated Raman Spectroscopy
… systems are measured by resonance transient Raman spectroscopy and provide information on the dynamics of the system following two-photon sequential excitation through mode-specific enhancements. Sequential excitation allows for optical control of the system by accessing more efficient …
