Abstract
A photoelectric device suitable for use as an image sensor includes a body of amorphous silicon and a pair of electrodes sandwiching the body. The amorphous silicon body includes at least one kind of oxygen, carbon, and nitrogen atoms and it has an ability to exhibit a predetermined level of photoconductivity for an optical bandgap of 2.0 eV or more. The amorphous silicon body may have either a mono-layered structure or a multi-layered structure. In the latter case, the body may have a p-i-n structure.
