中文摘要 | transient photoconductivity and its light-induced change were investigated by using a model 4400 boxcar averager and signal processor for lightly boron-doped a-si : h films. the transient photoconductivities of the sample were measured at an annealed state and light-soaked states. the transient decay process of the photoconductivity can be fitted fairly well by a second-order exponential decay function, which indicates that the decay process is related with two different traps. it is noteworthy that the photoconductivity of the film increases after light-soaking. this may be due to the deactivity of the boron acceptor b-4(-), and thus some of the boron atoms can no longer act as acceptors and drives e-f to shifts upward. consequently, the number of effective recombination centers may be reduced and so the photoconductivity increases. |
