Abstract

Measurements of the tunneling and phototunneling I-V and G-V characteristics have enabled the study of the distribution of states in the band-gap of hydrogenated amorpous silicon. It is found that regardless of the method of preparation and the material dopants there is a peak in the bulk and surface density of states which lies 0.45 eV below the conduction band edge. The density of states at the peak is concluded to be 10¹⁸ - 10¹⁹ cm^-3 eV^-1, decreasing by at least an order of magnitude for energies below and above this peak.
