The electronic and geometrical structures, in particular the electric field gradients (EFGs), of CdD 2 (D P, As, Sb) acceptor-donor pairs in Si and Ge are studied using the full potential Korringa-KohnRostoker Green’s function method. In addition, also neutral complexes ( CdD 0) and trimers ( CdD2 0) in Si are investigated. The EFG depends very sensitively on the large lattice relaxations induced by the defects and can be understood by a simple hybridization model. Our calculations are in good agreement with experimental results and provide a consistent picture of acceptor-donor complexes in Si and Ge.
