We study optical quantum transition line shapes (QTRSs) and optical quantum transition line widths (QTLWs) in relation to magnetic-field dependence properties of the electron-piezoelec 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 is 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 increasing properties of QTLW and QTLS of ZnS and Ge with the temperature and the magnetic fields. We also found the dominant scattering processes are the phonon emission transition process.
