Abstract

A unique model for the III-rich (001)-surface reconstruction of III-V semiconductors was established. The resulting model consists of subsurface III dimers and chains of atoms located at nonbulk sites along the [110]bulk direction at the surface. The developed model explains the discrepancy between (4 × 1) symmetry found earlier in STM experiments and c(8 × 2) diffraction patterns.
