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 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.
