Observation of a quasi-two-dimensional electron gas at an InSb/CdTe interface

Liquid-helium temperature transport and magnetotransport measurements on n-CdTe grown by molecular beam epitaxy on p-InSb substrates have demonstrated the presence of a quasi-two-dimensional electron gas in the InSb at the InSb/CdTe interface. The electron density and mobility in the channel can be varied by back gating.
