Abstract
The electronic properties of the In (→ Cd) acceptor are studied in polycrystalline germanium by the perturbed angular correlation method (PAC). The time independent anisotropy reveals a strong temperature dependence. This behaviour can be explained quantitatively by a model based on recombination processes at the Cd acceptor. The recombination rates depend on the annealing procedure of the samples, thus indicating a strong influence of the grain boundaries.
