摘要：
Different models for the GaSb-(001) surface reconstruction have been proposed on the basis of experimental observations in typical GaSb growth conditions (V/III flux ratio > 1). We have analyzed their relative stability by means of first-principles pseudopotential plane-wave calculations. We constructed the surface phase diagram as a function of the chemical potential of the elemental constituents to mimic different growth conditions.
