Summary:
Transient photoconductivity and ESR measurements were done to relate the ionized dangling bond density of thick hydrogenated amorphous silicon (a-Si:H) detectors. We found that only a fraction (/approximately/30--35%) of the total defect density as measured by ESR is ionized when the detector is biased into deep depletion. The measurements on annealed samples also show that this fraction is about 0.3. An explanation based on the shift of the Fermi energy is given. The measurements show that the time dependence of relaxation is a stretched exponential. 8 refs., 4 figs., 1 tab.
