Fine structure of cyclotron resonance in a two-dimensional electron system

Abstract

The authors discuss magnetoplasma and cyclotron resonances under microwave excitation in a high quality, GaAs/AlGaAs two-dimensional electron system. They observe that the cyclotron resonance originates as a pure resonance that does not hybridize with dimensional magnetoplasma excitations. The magnetoplasma resonances form a fine structure of the cyclotron resonance.
