Heterojunctions and Interfaces [PDF]
, 1991 The presence of an inversion or accumulation layer of charge, either electrons or holes, at the surface of certain heterojunctions was predicted many decades ago. This is true whether the heterojunction is between two semiconductors, such as in the high-electron-mobility transistor, or between a semiconductor and an oxide (or free space), such as in an

Self-Reconstructed Metal-Organic Framework Heterojunction for Switchable Oxygen Evolution Reaction.
Angewandte Chemie, 2022Designing metal-organic framework (MOF)-based catalysts with superior oxygen evolution reaction (OER) activity and robust durability simultaneously is highly required yet very challenging due to the limited intrinsic activity and their elusive evolution ...

Solid-State Electronics, 1965
Abstract Work is described which shows that layers of GaSbxAs1-x, GaxIn1-xAs and Mn2As of device quality can be produced on GaAs using a simple alloying technique. The use of these layers in making heterojunctions with GaAs for opto-electronic devices is suggested and some of their optical and electrical properties are discussed.

Shallow impurities in heterojunctions
Journal of Physics and Chemistry of Solids, 1992Abstract The shallow impurity states in Si/SiO 2 and GaAs/Ga 1− x Al x As heterojunctions are studied variationally using an improved Fang-Howard trial wave function originally proposed for the Si/SiO 2 system.

Theory of Semiconductor Heterojunctions
MRS Proceedings, 1982A short review of characteristic electronic properties of heterojunction interfaces is given. Band edge discontinuities and interface band structures for lattice-matched junctions are discussed in detail. The examples presented include non-polar and polar junctions as well as overlayer systems.
