摘要：
We report inefficient doping of hydrogenated amorphous silicon (a-Si:H) by group VI, sulfur double-donors. We also report the appearance of an optically-induced activation of sulfur-related donors, that are de-activated (or passivated) by hydrogen in annealed films of a-Si:H. In addition, we examine the possibility that this new metastability might be used to counteract the deleterious features of the Staebler-Wronski effect in a-Si:H.
