Observation and analysis of Fano-like lineshapes in the Raman spectra of molecules adsorbed at metal interfaces [PDF]

, 2015
Surface enhanced Raman spectra from molecules (bipyridyl ethylene) adsorbed on gold dumbells are observed to become increasingly asymmetric (Fano-like) at higher incident light intensity.

Uncoupled excitons in semiconductor microcavities detected in resonant Raman scattering [PDF]

, 2003
We present an outgoing resonant Raman-scattering study of a GaAs/AlGaAs based microcavity embedded in a p-i-n junction. The p-i-n junction allows the vertical electric field to be varied, permitting control of exciton-photon detuning and quenching of ...

Raman Scattering in Pathology

, 2013
Raman scattering is the inelastic scattering of light by chemical bonds, and can therefore show molecular specificity. It can be used both in pure spectroscopy mode, and in imaging mode. While many applications of Raman spectroscopy and imaging in the biomedical field have been so far demonstrated, the use of this technology for pathology applications ...

Electronic Raman scattering in Tl2Ba2CuO6+x: symmetry of the order parameter, oxygen doping effects, and normal state scattering

, 1998
Single crystals of the optimally doped, moderately and strongly overdoped high temperature superconductor Tl2Ba2CuO6+x (Tl-2201) with Tc=80, 56 and 30K, respectively, have been investigated by polarized Raman scattering.

Transient Stimulated Raman Scattering [PDF]

SIAM Journal on Mathematical Analysis, 1992
The authors consider the system of partial differential equations \[ {\partial u\over \partial\xi}= -zv,\;{\partial v\over \partial\xi}= \bar zu,\;{\partial z\over \partial\tau}= u\bar v- \gamma z \] which model the interaction of two laser beams with gases when the frequency difference between the beams corresponds to a resonance of the gas molecules.

Raman scattering in current carrying molecular junctions. A preliminary account

, 2008
This is a preliminary acount of a theory for Raman scattering by current-carrying molecular junctions. The approach combines a non-equilibrium Green's function (NEGF) description of the non-equilibrium junction with a generalized scattering theory ...

Intersubband electronic Raman scattering in narrow GaAs single quantum wells dominated by single-particle excitations [PDF]

, 2004
We measured resonant Raman scattering by intersubband electronic excitations in GaAs/AlAs single quantum wells (QWs) with well widths ranging from 8.5 to 18 nm.

Coherent Anti-Stokes Hyper-Raman Spectroscopy

Nature Communications
Coherent Raman scattering spectroscopies have been established as a powerful tool for investigating molecular systems with high chemical specificity. The existing coherent Raman scattering techniques detect only Raman active modes, which are a part of ...

Cavity-enhanced Raman microscopy of individual carbon nanotubes

Nature Communications, 2016
Enhancement techniques are a viable route to improve the intrinsically weak Raman scattering intensity. Here the authors demonstrate Purcell enhancement of Raman scattering in a tunable, high-finesse microcavity and use it for Raman imaging of individual

A micro-magneto-Raman scattering study of graphene on a bulk graphite substrate

, 2014
We report on a magneto-Raman scattering study of graphene flakes located on the surface of a bulk graphite substrate. By spatially mapping the Raman scattering response of the surface of bulk graphite with an applied magnetic field, we pinpoint specific ...
