Abstract

Cyclotron resonance (CR) of two-dimensional electron gases (2DEG) in GaAs/AlGaAs heterojunction was studied by the gate voltage ratio spectrum measurement technique. The oscillation behaviors of the intensity of the CR peaks, the electron effective mass, scattering time and mobility obtained by fitting the CR line shape with the magnetic field due to the resonant subband Landau level coupling (RSLC) were observed. Several intersubband energies with high quantum index were measured by this RSLC method at different gate voltage. The results are in good agreement with the self-consistent calculations including the depolarization shift and the exciton effect correction.
