ANOMALOUS MAGNETORESISTANCE IN P-TYPE QUANTUM-WELLS

The effects of intensive interlevel transitions in quantum wells (QWs) and strong spin-orbit interactions on weak localization are considere d. Anomalous magnetoresistance in classically weak fields is calculate d for p-type QWs based on A(3)B(5) semiconductors. It is shown that th e sign of magnetoresistance changes with varying of the doping level a nd the role of the intersubband transitions in weak localization effec ts depends dramatically on a view of the scattering potential.
