Two-dimensional electronic structure in InAs-GaSb superlattices
Abstract
We have achieved by molecular-beam-epitaxy the new type of superlattice of InAs and GaSb whose energy gaps do not overlap. The observed Shubnikov-de Haas oscillations manifest the two-dimensional electronic subband structure, corroborating theoretical calculations. The deduced electron mass is enhanced primarily as a result of the strong nonparabolicity in the conduction-band of InAs. © 1978.
