Abstract
We report the first observation of saturation of the defect density and of the photoconductivity in hydrogenated amorphous silicon after light soaking with laser pulses. The saturated defect density reaches approximately the same value as the density established by soaking with continuous light. Comparison of pulsed with cw light-soaking experiments, via an effective light-soaking time, shows the use of pulsed light to be equivalent to that of continuous wave light, in defect saturation.Keywords
