1.
Blocking of the polaron effect and spin-split cyclotron resonance in a two-dimensional electron Gas
Wu XG; Peeters FM; Wang YJ; McCombe BD.

ABSTRACT

Cyclotron resonance (CR) of high density GaAs quantum wells exhibits well-resolved spin splitting above the LO-phonon frequency. The spin-up and spin-down CR frequencies are reversed relative to the order expected from simple band nonparabolicity. We demonstrate that this is a consequence of the blocking of the polaron interaction which is a sensitive function of the filling of the Landau levels.
