摘要
A junction of emeraldine salt (ES [BF4-]) doped by [BMIM] [BF4] may be preferred over the other junctions due to its low ideality factor and maximum rectification ratio. Schottky barrier diode based on composite of polyaniline (ES [BF4-]) with polystyrene has been created and characterized using aluminium as Schottky contact and argent as an ohmic contact. The observed current-voltage characteristics can be satisfactorily fitted using the modified Schottky equation. Capacitance-voltage (C-V) in reverse bias and current-voltage (I-V) plots indicates a rectification. Various junction parameters were calculated from the temperature dependent I-V and C-V data and discussed. These results indicate that the composite materials have better mechanical strength and diode quality compared to the pure semiconducting polymer.
