Infra-red cyclotron resonance of 'crossed' band gap superlattices at magnetic fields of up to 150T
Proceedings of SPIE - The International Society for Optical Engineering 2104 (1993) 638-639
Abstract:
This paper presents an investigation of the effect of layer periodicity and magnetic field on the band gap of InAs/GaSb and InAs/GaInSb superlattices. The cyclotron resonance (CR) of these samples has been studied using CO2 and CO lasers which produce wavelengths of around 10μm and 5μm respectively. Pulsed magnetic fields of up to 150T with a duration of 5μsec were generated using a destructive, single-turn coil magnet and the transmitted radiation measured using a fast-response HgCdTe detector. In conclusion, the authors present direct evidence for the semimetal to semiconductor transition in type II superlattices caused by the formation of periodicity dependent subbands and also by the uncrossing of the electron and hole Landau levels at high magnetic fields.BAND OFFSETS IN STRAINED INGAASP/INGAASP QUANTUM-WELL OPTICAL MODULATOR STRUCTURES
