Combined influences of temperature, pressure, and alloy-composition on magneto-optical properties of the semi-parabolic well under all four different phonon models

Abstract

In this study, combined influences of the pressure, alloy composition, and temperature on the magneto-optical properties of the semiparabolic well under all four different phonon models, including three confining phonon models are considered in detail through the magneto-phonon resonance oscillation (MPRO). The magneto-optical transport absorption power (MOTAP) and MO-conductivity tensor (MOCT) expressions are obtained utilizing the method of operator projection. Simultaneously the profile method also is used in order to measure the inter-subband absorption linewidth. Our calculated result shows that (i) the aluminum composition y has significant effect on the position of the resonant peak; (ii) the absorption line-width as a function of the Al-composition, temperature of electron, and hydrostatic pressure for all four models of phonons; (iii) the influence of the Al-composition, temperature of electron, and pressure on the intersubband absorption line-width is different for each of phonon model; (iv) our present result is fairly consistent with experimental measurement; (v) combined effects of the aluminum composition, the temperature of electron, and the hydrostatic pressure on the intersubband absorption line-width of the semiparabolic QWs are important when the phonon confinement is taken into consideration.
