Cyclotron resonance in the Poschl-Teller quantum well under the influence of the asymmetric parameters

In this article, a detailed study of the influence of the asymmetry parameter of the Poschl-Teller potential quantum wells (PTPQW) on the cyclotron resonance absorption (CRA) power and the half-width or the full width at half maximum (FWHM) of the CRA-peak is reported utilizing the projection operator and profile methods, respectively. The main results of the research show that (i) the CRA-power in the PTPQW is affected strongly by the asymmetrical parameter A; (ii) the FWHM of the CRA-peak in the PTPQW as functions of the PTPQW-width L, the magnetic field B, the electron concentration ne, the temperature T, and the Landau level n at several values of the asymmetrical parameter A; (iii) the FWHM of the CRA-peak in the PTPQW always increases with the increasing asymmetrical parameter A; (iv) the obtained results for the Poschl-Teller QW are compared with those for the rectangular QW. (v) the PTPQW is a model which can yield promising magneto-optical properties, including the CRA-power and the FWHM of the CRA-peak for potential applications in the future to optoelectronic devices. The results of the present theoretical research are well consistent with those of the previous experimental one.
