Application of Raman spectroscopy analysis in unconventional natural gas reservoirs – density and pressure dependence on Raman signal intensity

Role of Symmetry in Raman Spectroscopy of Unconventional Superconductors

The role of symmetry of the inelastic light scattering amplitude, the superconducting energy gap, and the underlying Fermi surface manifold on the Raman spectra of unconventional superconductors is discussed in detail. Particular emphasis is placed on both single and bi-layer superconductors. It is found that the B1g channel may be the most sensitive to doping due to the role of the Van Hove si...

A note on distance dependence in surface enhanced Raman spectroscopy

It is appreciated that the surface enhanced Raman signal falls away rapidly from the substrate surface that provides the dominant electromagnetic enhancement. As many bio-molecules of interest are large, it is important to establish for any practical surface the usable distance from the surface at which molecules can still be detected. Using monolayer ssDNA arrays with three adenine bases close...
