Anomalous Magnetoresistance in Multy-Level 2D Systems
Abstract
A weak localization is a quantum interference of waves propagating through the closed trajectory in the opposite directions. This interference may be destroyed by different wave phase breaking processes: magnetic field, inelastic processes, spin relaxation etc. These mechanisms give additive contributions in the total interference breaking rate. One can show that the role of the intersubband transitions leads to the averaging of the pammeters which defines the weak localization. The way of the averaging depends on the relation between the inteflevd transition time and the times of phase breaking due to other processes. tn intensively investigated QWs with a few filled subbands of size quantization this relation can change in wide range. tn this report the weak localization theory for n- and p- type QWs in which carriers occupy a few size-quantized levels is proposed.
