A Proposal of Single Quantum Well Transistor (SQWT) –Self-Consistent Calculations of 2D Electrons in a Quantum Well with External Voltage

Abstract

New devices are proposed with an operation principle based on the wave function control of two dimensional electron gas in a single quantum well composed of double heterostructures, for example, AlGaAs/GaAs/AlGaAs. Self-consistent calculations indicate that the current channel of the two dimensional electrons can be easily confined in one of the heterojunction surfaces by applying an external voltage. We show that the mechanism has the capability of fabricating high speed logic devices.
