Charge carrier mobility in organic semiconductors

Two effects are usually discussed with respect to the field dependence of the charge carrier mobility in organic semiconductors [1,2, 4-7]. One of them is the apparent decrease of the drift mobility with rising field at relatively high temperatures [1, 2, 4-7, 68-70]. The other is the strong increase of the drift mobility with rising field at low temperatures. 

An unconventional method of determination of charge carrier mobility in organic semiconductors is based on admittance...
