Abstract
This paper reports the result obtained during fiscal 1994 on research on an optical study of optoelectronic properties of amorphous silicon and its carrier dynamics. Studies have been performed on elucidation of the optoelectronic conversion mechanism in an a-Si film p-i-n junction system and the relationship of the mechanism with the optoelectronic properties. In the studies, optically induced defect level distribution was evaluated by using the modulated optical current spectroscopy, and confirmation was made on model forecast and qualitative agreement, such as large increase in neutral defect levels in association with beam irradiation. In research on elucidation of a film forming mechanism for a-Si based alloys, and material property control, a high-sensitivity reflective infrared spectroscopy was used to observe mechanisms such as treatments and processes given in device fabrication. In research on optical and optoelectronic properties of an s-Si alloy thin film by using the modulated spectroscopy, a new evaluation technology dealing with amorphous semiconductors was developed. The technology separately evaluates carrier migration factors of electrons and holes by combining polarization angle dependence of electro-absorption signals with hole migration measurements. 4 figs.
