Abstract

Slow magneto-oscilations of the conductivity are observed in a 75-nm-wide quantum well at heating of the two-dimensional electrons by a high-intensity surface acoustic wave. These magneto-oscillations are caused by intersubband elastic scattering between the symmetric and asymmetric subbands formed due to an electrostatic barrier in the center of the quantum well. The tunneling splitting between these subbands as well as the intersubband scattering rate are determined.
