Abstract
A transport equation has been fitted to time-of-flight transient photocurrent signals of molecularly doped polymers in order to obtain both diffusion coefficient (D) and drift mobility ((mu) ) simultaneously. The logarithm of (mu) increased linearly with the square root of the electric field. The negative field dependence on the square root of the electric field at a low electric field that had been reported appeared to superimposing of drift and diffusion. The logarithm of D increased linearly with the square root of the electric field. The logarithm of D decreased linearly with T<SUP>-2</SUP>.
