Abstract:
The effect of microwave radiation on low-temperature electron magnetotransport in a square antidot lattice with a period of $d \approx 0.8\,\mu$m based on a GaAs quantum well with two occupied energy subbands $E_1$ and $E_2$ is investigated. It is shown that, owing to a significant difference between the electron densities in the subbands, commensurability oscillations of the resistance in the investigated antidot lattice are observed only for the first subband. It is found that microwave irradiation under the cyclotron resonance condition results in the formation of resistance oscillations periodic in the inverse magnetic field in the region of the main commensurability peak. It is established that the period of these oscillations corresponds to the period of magneto-intersubband oscillations. The observed effect is explained by the increase in the rate of intersubband scattering caused by the difference between the electron heating in the subbands $E_1$ and $E_2$.
