It was pointed out that Se donors in n-type material were passivated by exposure to a H plasma. Thermal reactivation of the passivated donors was investigated at temperatures ranging from 154 to 191C. By using the electric field of a reverse-biased Schottky diode structure, the drift of thermally dissociated H as a negatively charged species was demonstrated. The thermal dissociation of the SeH complex obeyed first-order kinetics, with a dissociation energy of 1.52eV.
