Symmetrization of the trimer model for Si(111) 7×7

View publication

Abstract

A symmetrized extension of the trimer model for the Si(111) 7×7 structure is presented. It exhibits new features such as sixfold coordinated Si atoms which are not unusual in Si chemistry but have not been considered in previous structural models. Atomic coordinates are optimized by a Keating-type strain energy minimization and the structure factor for transmission electron diffraction is calculated. © 1985.
