Abstract
e GaN and other group III nitrides have great importance in a wide range of technological applications. Difficulty in growing good quality epitaxial GaN currently prevents the full technological potential of this material. The ab initio studies presented employed the CASTEP implementation of the pseudopotential-plane wave method in order to obtain the minimum energy configurations of various GaN (0001) 2×2 surfaces involving N atoms. Based on these results we have characterized the effect of N in the adlayer surface and the stability dependence with number of substitutions as a function of the model employed and the possible surfactant character of some of the added atoms.
