Cyclotron Resonance in High Magnetic Fields

چکیده
We review recent cyclotron resonance studies of semiconductors performed in high magnetic fields. This traditional semiconductor characterization method has been used to study some of the recentlydeveloped materials systems, including ferromagnetic III-V semiconductors and two-dimensional electron gases formed in InSb/InAlSb and GaN/AlGaN heterostructures. These studies have not only provided an insight into the basic properties of these technologically-important materials but also revealed new types of splittings that can shed light on carrier-interaction effects on cyclotron resonance. In addition, we discuss new aspects of spin-split cyclotron resonance in electron systems with large spin splittings such as InAs/AlAs and InAs/GaSb as well as the polaron cyclotron resonance in II-VI compounds in megagauss magnetic fields. Finally, some of the new future directions employing far-infrared magneto-optical spectroscopy are mentioned.
