Exciton Coupling

Exciton–phonon interaction in quasi-2D material was investigated. It was shown that longitudinal optical phonon, rather than acoustic phonon-exciton coupling dominated the enhancement of exciton–phonon coupling strength.

AbstractWe have studied the effects on the phonon spectrum and on the electron-longitudinal optical phonon scattering in GaN/AlN and GaAs/AlAs quantum wells. Phonon modes and potentials have been calculated for both systems. Results for emission due to electroninterface phonons interactions are presented. We will discuss the implications for relaxation times and electron mobility due to modified LO-phonon scattering in both systems.
