Antilocalization and spin-orbit coupling in the hole gas in strained GaAs/InxGa1-xAs/GaAs quantum well heterostructures -: art. no. 165312

Anomalous low-field magnetoresistance in p-type strained quantum wells is studied. It is experimentally shown that the Bychkov-Rashba mechanism leads to the cubic in quasimomentum spin-orbit splitting of the hole energy spectrum and the antilocalization behavior of low-field magnetoresistance is well described by the Hikami-Larkin-Nagaoka expression.
