Abstract

Submonolayer structure has been observed using reflection high-energy electron diffraction during room-temperature deposition of Al onto (2×4) reconstructed GaAs(001) surfaces prepared by molecular beam epitaxy. This structure with a (4×1) symmetry occurs after ∼0.25 monolayer of Al deposition. It is growth-rate independent, reproducible, and stable. This result shows that there is a strong, directionally dependent adatom-adatom interaction at submonolayer coverages.
