Abstract

After rapid cooling from 210°C a characteristic electron spin resonance (ESR) and a characteristic below-gap optical absorption have been observed to grow with time at room temperature in hydrogenated amorphous silicon (a-Si:H). Both the increased ESR and the increased optical absorption anneal at temperatures above about 100°C. These unexpected results may have important consequences for our understanding of the electronic properties of a-Si:H.
