| Abstract: | The growing curve of light-induced dangling bonds under illumination has been observed for various intensities of illumination in a-Si:H. It is fitted to a stretched exponential function and then two parameters β and τ involved in the function are estimated as a function of saturated dangling bond density  . The experimental values of β, τ, and  are compared with those calculated based on our model of light-induced defect creation in a-Si:H. |
