Atomic structure of (100) surfaces of zincblende compound semiconductors

This paper provides an overview of our current understanding of atomic geometries of (100) surfaces of III-V, II-VI and I-VII zincblende structure semiconductors. The origins of atomic reconstructions of polar surfaces are reviewed. Fundamental principles are described from which the main aspects of reconstructions at (100) surfaces can be derived. These principles are used to explain and predict stoichiometries and atomic arrangements on these complex surfaces. The most recent structural models of (100) surfaces are reviewed in light of these principles.
