Chalcogenide amorphous semiconductor diodes were fabricated using low-temperature thermal diffusion techniques. Anomalous diffusion profiles of Cd ions were observed by secondary ion mass spectroscopy. Two opposite potential barriers were formed owing to a peculiar diffusion profile of Cd; thus, the rectifying effects became poor. A high density of vacancies and dislocation-like defects, especially in the surface region, is considered to cause anomalous diffusion profiles of Cd ions.
