Abstract:
The method of numerical simulation is used to fit the relationship between
the photoconductivity in films and the illumination time. The generation and
process rule of kinds of different charged defect states during illumination
are revealed. It is found surprisingly that the initial photoconductivity
determines directly the total account of photoconductivity degradation of
sample.
