In this paper,we study the effects of annealing on photoconductivity of GDa-SiN_x:H films.By measuring the photoconductivity,we can give the absorptioncoefficient and width of tail states of samples,and is it indicated that the annealingis an effective method which can clear up the localized states produced by randomaccumulation
