Abstract
The atomic geometry of the CuCl(110)-(1×1) surface is determined by dynamical analysis of low-energy electron-diffraction intensities. This surface undergoes a relaxation characterized by a ∼30° Cu-Cl surface bond rotation, a 0.15 Å contraction of the top-to-second layer distance, and a 0.4 Å horizontal displacement of Cl relative to Cu. The relaxation is consistent with the ‘‘universal’’ structure deduced from the analysis of cleavage surface of tetrahedrally coordinated III-V and II-VI compounds, thereby revealing that this featuare of the structure does not depend significntly on the ionicity of the compound.This publication has 15 references indexed in Scilit:
