Cyclotron resonance in an InAs-GaSb superlattice
Abstract
Optical transmission in the far infrared region in an InAs-GaSb superlattice is studied as a function of magnetic field and frequency. Cyclotron resonance is observed for electrons confined in the InAs conduction band whose ground state is shifted to higher energy due to the periodic superlattice potential. These measurements confirm the calculated quantisation of the energy levels in a superlattice by ascertaining the effective mass directly. © 1979.
