Absorption power and linewidths in quantum wells with Poschl-Teller hyperbolic potential in magnetic fields

Abstract

Abstract: Explicit expressions for magnetoconductivity and absorption power in hyperbolic quantum well with P¨oschl-Teller potential type under the influence of a static magnetic fielf was obtained using the state-independent operator projection technique. The dependence of absorption power on photon energy was calculated and graphically plotted. From the graph of absorption power as a function of photon energy, we investigated the optically detected magneto-phonon resonance effect and the spectral linewidths of the resonance peaks. The obtained results show that the appearance of resonance peaks satisfies the law of conservation of energy, and the spectral linewidths of the resonant peaks vary with temperature, magnetic field intensity, and well parameters.
