Cyclotron resonance in corrugated lateral superlattices

We investigate the cyclotron resonance of corrugated lateral superlattices with ultrashort period View the MathML source grown on (7 7 5)B GaAs substrates. In addition to the broad dips of cyclotron resonance compared with those of the unmodulated samples, the magnetic field dependence of observed cyclotron resonance spectra shows the anticross behavior or more complicated behavior. Several possible mechanisms on this behavior are discussed.
