Abstract:
The theory of the Shubnikov-de Haas effect is presented for quasi-2D systems when several subbands of size quantization are occupied. The temperature behavior of oscillation spectrum is considered. It is shown that the main harmonics with frequencies defined by subband fillings damp exponentially and the non-damping oscillations with differential frequencies proportional to energy gaps between subbands manifest themselves. They are harmonics, which became dominating at the following increasing of temperature.
