| Abstract(in English) | An equation for the shape of transient photocurrent has been introduced and fitted to time-of-flight signals of molecularly doped polymers. By this procedure, dfffusion coefficient (D) and drift mobility (μ) have been obtained simultaneously. An anomalous field-assisted D was observed.Therefore, the value of D/μ is large. This property of the molecularly dopedpolymer is attractive for the photorefractive materials. Space-charge in the organic photorefractive material has been produced by exnernal applied voltage. In a molecularly doped polymer system, the voltage need not be applied, because the value of D/μ is large. In addition, we confirmed this by the experiment. |
