Abstract

The density of states (DOS) has for the first time been calculated throughout the entire bandgap region of undoped amorphous silicon from quasi-static capacitance-voltage (QSCV) measurements using MOS structures. The QSCV DOS is compared with the DOS obtained by the field-effect method. It is shown, that the coexistence of states of a different nature at the same bandgap level can be revealed by the temperature dependence of low frequency MOS CV measurements.
