LOW-FIELD HOLE MOBILITY IN A PHOTOREFRACTIVE POLYMER

摘要

We present the time-of-flight measurements of hole mobility in a photorefractive polymer composite as a function of temperature and applied electric field. The analysis shows that the temperature dependence of the low-field mobility is in apparent disagreement with the predictions of the Gaussian disorder model and also with polaron models.
