摘要
A Schottky diode with configuration Pt/PAn-PVC/In is fabricated using composite of polyaniline with polyvinyl chloride (PAn-PVC). Current-voltage (I-V) plots were non-linear and capacitance-voltage (C-V) plots were almost linear in reverse bias indicating rectification behavior. The observed current-voltage characteristics can be satisfactorily fitted using the modified Schottky equation. Various junction parameters were calculated from the temperature-dependent I-V and C-V data and discussed. The carrier concentration from 1/C-2-V plots varies from 2.70 x 10(16) cm(-3) at room temperature to 4.62 x 10(16) cm(-3) at 343 K. Impedance studies shows the R(RC)(RC) equivalent circuit for the fabricated Schottky diode. (C) 2004 Elsevier Ltd. All rights reserved.
