The analysis of photoenhanced current in organic films: the influence of charge carrier diffusion

Effect of shallow traps on admittance spectra of the system carrying SCLC and on values of charge carrier mobility extracted from susceptance

“…All simulations were performed for a thin organic layer with the following parameters: d = 100 nm, e = 4, l = 10 À4 cm 2 V À1 s À1 , m = 10 12 s À1 , c ft = 10 À9 cm 3 /s. For trapping rate constant we take only one value, which we find as typical for organic materials [10,20,21], however in general the value of c ft depends on material and on origin of traps. The active area of electrodes was taken as equal to 10 mm 2 .…”
