Frequency domain identification of NPB transporting properties of organic semiconductor based on particle swarm optimization algorithm


In order to study the carrier transporting properties in organic semiconductors (OSC), a single device with structure ITO/NPB/Ag is made, and the corresponding admittance model in theory is built.A group of impedance samples under different DC bias voltages of the device are obtained by small sinusoidal signal frequency test method. The fitness function of… (More)
