Abstract

Ab initio calculations on hydrogen complexes with Mg and Be impurities in c-BN are reported. We find that both impurities are acceptors and both bind H to form passive defects. However, their structures are different. For Be-H, the H atom lies at a puckered bond-centre configuration similar to that of C-H in GaAs, while in Mg-H, the H atom lies at a site anti-bonding to a N neighbour of the impurity. The hydrogen-related vibrational modes of the two complexes are also reported.
