Abstract

The first determination of the atomic geometry of the (110) surface of InSb is reported. The structure is determined by comparing dynamical calculations of elastic low-energy electron diffraction (ELEED) intensities with those measured at T equals 150 K. The structure is analogous to that of covalently bonded GaAs(110) but different from that of ZnTe(110) which exhibits a more ionic bonding. It is concluded that highly covalent zincblende-structure compound semiconductors exhibit reconstructions of their (110) surfaces characterized by (1) large bond rotations in the uppermost layer, with the anion moving outward and cation inward, (2) small bond-length alterations (i. e. , a few percent or less), and (3) distortions from the bulk geometry which penetrate at least two atomic layers in from the surface.
