Phonon self-energy effects due to superconductivity in Bi2Sr2CaCu2O81d
Raman scattering of A1g phonons in Bi2Sr2CaCu2O81d single crystals ~d50.13, Tc586 K! has been measured as a function of temperature. We report an anomalous softening in the frequency and a decrease in the linewidth of the A1g phonon at 290 cm 21 ~O1,2 c-axis in-phase vibration! below Tc . We also confirm a smaller anomalous softening in the frequency of the A1g phonon at 465 cm 21 ~O3 c-axis vi...
متن کاملRaman-Brillouin electronic density in short-period superlattices
We analyze and interpret resonant Raman-Brillouin scattering by folded acoustic vibrations in short-period GaAs/AlAs superlattices. Analysis of the spectra and their resonance behavior is performed using a RamanBrillouin electronic density constructed by combining thousands transitions between electronic eigenstates of the system according to their weight in the light-scattering process. We sho...
متن کاملPolarization-Dependent Surface Enhanced Raman Scattering from Silver 1D Nanoparticle Arrays
Arrays of linear, one-dimensional (1D) silver nanoparticle rows have been synthesized that demonstrate strong surface enhanced Raman scattering (SERS) that is dependent on the polarization of the incident electromagnetic radiation. Ordered arrays of 1D rows of spherical silver nanoparticles were fabricated on highly oriented pyrolytic graphite (HOPG) by physical vapor deposition (PVD) at 400 °C...
متن کاملRESONANT RAMAN SCATTERING IN NaV2O5 AS A PROBE OF ITS ELECTRONIC STRUCTURE
In order to investigate the origin of the phase transition observed in NaV2O5, as well as its electronic structure, we have measured Raman intensities as a function of the laser wavelength above and below the phase transition temperature. In the polarized Raman spectra at room temperature we observe resonant enhancement of the 969 cm phonon mode when the laser energy approaches 2.7 eV, presumab...
متن کاملInvestigation of Scalar Modulation Instability in the Presence of Raman Scattering in Photonic Crystal Fibers
In this paper, by including Raman scattering in the coupled-mode equations, the scalar modulation instability in photonic crystal fibers is investigated. The evolution of the pump, Stokes and anti-Stokes waves along the fiber as well as the conversion efficiency for two cases, with and without Raman effect, are studied. The effect of anti-Stokes seed and the pump depletion on the evolution of S...
