In the measurements of space-charge limited current (SCLC) transport in disordered organic semiconductors, it is often observed that carrier mobility depends on bias voltage. Two continuous models have been applied for the description of this dependence. One interpretation assumes the charge carrier mobility dependent on the local electrical field. In the other one, the mobility at the transport state...
Space-charge limited current transport in organic devices, relevant to the operation of a range of organic optoelectronic devices, is analyzed in the frequency domain. The classical multiple trapping picture with one transport state and one trap level is used as the basis for the descriptions. By varying the energetic and kinetic properties of the traps, we show that the admittance and the capacitance...
