New Evidence for Defect Creation by High Optical Excitation in Glow Discharge Amorphous Silicon
TL;DR: In this article, the authors presented evidence for the creation of dangling bonds by high optical excitation at low temperatures through time-resolved luminescence measurements and ESR measurements in glow discharge amorphous silicon.
Journal ArticleDOI
Fatigue effect in luminescence of glow discharge amorphous silicon at low temperatures
TL;DR: In this article, glow discharge amorphous silicon at 4.2 K and 77 K was found to have a fatigue in luminescence, which was not recovered by infra-red illumination, but by heating the sample at higher temperatures.
Journal ArticleDOI
Microscopic Mechanism for the Photo-Creation of Dangling Bonds in a-Si:H
TL;DR: In this article, a microscopic model for the photocreation of silicon dangling bonds is presented, taking into account the combined effects of breaking of weak bonds, Si-H bond switching, and H-tunneling which occur under intense optical excitation.
Journal ArticleDOI
Superconductivity and metal-insulator transition in amorphous Si1−xAux system
TL;DR: In this article, the electrical conductivity of metallic amorphous Si 1− x Au x films was measured down to 10 mK and superconducting transition was observed in a certain range of Au content.
