- Experimental results on microwave-induced magnetoresistance oscillations in two-dimensional electron systems show a similar behavior regarding temperature and microwave frequency. It is found that these oscillations tend to quench when frequency or temperature increases, approaching magnetoresistance to the response of the dark system. In this work, we show that this experimental behavior can be addressed on the same theoretical basis. Microwave radiation forces the electron orbits to move back and forth being damped by interaction with the lattice. We show that this damping dramatically depends on microwave frequency and also on temperature.
