Abstract
In this paper, after considering the dependence of quantum efficiency of charge generation, carrier mobility, and trapping rate on the applied electric field, the relations of steady state space-charge field and response rates of space-charge field are discussed with respect to the applied electric field in photorefractive polymers. It is found that the steady state properties of the space-charge field with respect to the applied electric field are in agreement with those of inorganic photorefractive crystals. However, for the transient processes, there are different function forms between the response rates and the applied electric field, such as superlinear functions and sublinear functions. Also, the response rates are determined by the properties of traps.
