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 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 C-H in GaAs, while in Mg-H the H atom lies at an anti-bonding site to an N neighbour of the impurity. The hydrogen related vibrational modes of the two complexes are also reported. © 2001 Elsevier Science B.V. All rights reserved.
