Surface phase diagram of recently proposed GaAs(0 0 1)-(2 Â 4)g is systematically investigated by using our ab initio-based approach. We focus on the (4 Â 7) domain consisting of c(4 Â 4)-like and (2 Â 4)-like regions to clarify surface dimer constituents as functions of temperature T and As (As 2 a

Surface phase diagrams of GaN(0 0 0 1)-(2 Â 2) and pseudo-(1 Â 1) surfaces are systematically investigated by using our ab initio-based approach. The phase diagrams are obtained as functions of temperature T and Ga beam equivalent pressure p Ga by comparing chemical potentials of Ga atom in the vapo
