Optically detected magneto-phonon resonance linewidths in cylindrical quantum wire

Abstract

In this paper, the general analytic expression for absorption power of a electromagnetic wave caused by confined electrons in cylindrical quantum wire (CQW) are obtained. Optically detected magneto-phonon resonance (ODMPR) effect in a specific GaAs/AlAs CQW is investigated. Anomalous behaviors of the ODMPR spectra are discussed. From the graphs showing the dependence of the absorption power on the photon frequency, we obtain ODMPR-linewidths as profiles of curves. Computational results show that the ODMPR-linewidths are directly proportional to magnetic field, temperature and decrease with wire's radius.
