title: Microwave-induced resistance oscillations versus magnetoabsorption in two-dimensional electron systems: role of temperature.
abstract: Magnetoabsorption and microwave-induced resistance oscillations in two-dimensional electron systems are calculated with the same theoretical approach, the microwave-driven Larmor orbit model. This theory, which first was developed to obtain microwave-induced zero resistance states and resistance oscillations, permits us also to calculate the microwave magnetoabsorption. We study the influence of temperature on magnetoabsorption, obtaining a progressive quenching of the absorption peak as temperature increases. We compare this quenching with the similar behavior that the microwave-induced magnetoresistance oscillations present. This quenching is explained in terms of electron-acoustic phonons scattering for both effects.
