Abstract:
We study the properties of high mobility GaAs/GaAlAs quantum well
structure by monitoring the microwave induced changes in the
low-temperature photoluminescence of the 2DEG as a function of the
external magnetic field. The most pronounced changes are observed at
cyclotron resonance conditions, but weak features are also visible at
cyclotron resonance replicas. Possible observation of microwave induced
shift in the Landau-level structure of magneto-photoluminescence is
reported in addition to the effects of carrier heating which are
conventionally bracketed together with microwave irradiation. (c) 2006
