摘要: The plane-wave pseudopotential method is used to calculate structural properties for wurtzite and zinc-blende AlN InN using large basis sets treating the indium 4[ital d] electrons as valence. These calculations, together with corresponding ones GaN [A. F. Wright J. S. Nelson, Phys. Rev. B 50, 2159 (1994)], yield a consistent set of well-converged AlN, GaN, InN. In particular, measured lattice mismatch among these compounds---essential an accurate description alloy properties---is well reproduced.
