Chapter 13: Staebler-Wronski Effect: Physics and Relevance to Devices: Physics and relevance to devices

Both the creation efficiency and kinetics of light-induced defects vary relatively little over a wide temperature range down to liquid He temperature. They are not governed by the competition between bimolecular and defect recombination channels. This is evidenced by sublinear time dependences of defect creation at low temperatures and at high photocarrier generation rate G where the bimolecular recombination dominates. These results indicate that defect creation is not triggered by the recombination events that dominate in the bulk. Rather, it might be triggered by recombination processes in special isolated regions such as near voids, in H-rich or H-poor regions, etc.
