Exciton-mediated one-phonon resonant Raman scattering from one-dimensional systems
نویسندگان
چکیده
We use the Kramers-Heisenberg approach to derive a general expression for the resonant Raman scattering cross section from a one-dimensional 1D system explicitly accounting for excitonic effects. The result should prove useful for analyzing the Raman resonance excitation profile line shapes for a variety of 1D systems including carbon nanotubes and semiconductor quantum wires. We apply this formalism to a simple 1D model system to illustrate the similarities and differences between the free electron and correlated electron-hole theories.

Resonant Raman scattering in Ga(As, P) mediated by (localized exciton-LO phonon) complex
Resonance light scattering experiments in polar crystals at energies corresponding to Eex + n012703C9LO have suggested that dressed excitons are the relevant intermediate states. Configuration coordinate model is applied to calculate the resonance Raman spectrum (intensity of phonons lines as a function of incident frequency) of the mixed crystal GaAs0.2P0.8 and compared with experimental resul...

We treat resonant Raman scattering via the multiphonon exciton transitions in cylindrical quantum dots with a parabolic confinement in the lateral direction and with a finite rectangular interface-barrier confinement in the axial direction. The optical phonons and the electron-phonon interaction are considered within the multimode dielectric model. The model exploits both electrostatic and mech...

Photoluminescence excitation (PLE) spectroscopy of single-walled carbon nanotubes (SWNTs) has been extensively studied for characterization of their unique electronic properties due to the one-dimensionality. The precise evaluation of exciton transition energy is essential for experimental assignments of optical absorption, photoluminescence, and resonant Raman scatterings. Here, several experi...
متن کاملRaman spectroscopy and photoluminescence of ZnTe thin films grown on GaAs
We report resonant Raman scattering and photoluminescence ~PL! measurements on two ZnTe thin films grown by molecular-beam epitaxy on GaAs substrates with thicknesses around 0.5 and 1.0 mm. The data have been obtained by using the different excitation energies of an Ar laser to distinguish Raman from PL and analyze resonant effects. The characteristic features of the low-temperature PL spectra ...
