Properties of the optical quantum transitions of ZnS and Ge for an electron-piezoeletric interaction system under two circularly oscillating fields

Abstract

We study the optical quantum transition line shapes (QTLSs) and the optical quantum transition line widths (QTLWs) in relation to magnetic-field-dependent properties of the electron-deformation potential phonon interaction system. We consider two systems — one is subject to right circularly oscillating external fields and the other is subject to left circularly oscillatory external fields. The main purpose of this work is to compare QTLSs, which indicate absorption power, in the two oscillating external fields. Our results indicate that the QTLSs of right circularly oscillating external fields are larger than the QTLSs of left circularly oscillating external fields while the opposite result is obtained for the QTLWs. Through the analysis of this work, we found the properties of the QTLW and the QTLS of ZnS and Ge increased with increasing temperature and the magnetic fields. We also found the dominant scattering process to be the phonon emission transition process.
