Three-dimensional character of semimetallic InAs-GaSb superlattices

View publication

Abstract

High-field, far-infrared magneto-absorption experiments are performed in semimetallic InAs-GaSb superlattices. The spectra exhibit extensive oscillations of cyclotron resonance and interband absorption from valence to conduction subbands. Transitions at both the center and the boundary of the superlattice zone are observed, from which the width of the ground conduction subband is obtained, demonstrating directly its three-dimensional character. © 1981.
