Abstract

In summary our results show that photoconductivity and optical absorption under cyclotron resonance conditions in high purity n-GaAs are more complex than it has been assumed previously. As cyclotron resonance can only be measured with non zero free electron concentration, and because the 2p – shallow donor level remains below the N=0 Landau level for all magnetic field strengths, a certain ...
