Far Infrared Magneto-optical Studies of Shallow Impurities in GaAs/AlGaAs Multiple-Quantum-Well Structures
Infrared and far infrared (FIR) magnetospectroscopy has been an important tool for the study of semiconductors for more than 30 years. With advances in materials growth techniques high quality, thin semiconductor films and repeated structures with compositional control in the growth direction on the scale of one or two monolayers, and well-controlled selective doping can be produced. These techniques have been used to grow structures both for basic physical studies and for novel device applications. Detailed understanding of the nature of the impurity states in these structures is important in both areas.
