Schottky diodes based on some semiconducting polymers

Recently there has been growing interest in the fabrication of devices using organic electrical conductors. In this paper, we report the fabrication of Schottky diodes based on metal-semiconducting organic polymer/Pt and metal-semiconducting organic polymer/carbon systems. The conducting polymer used was polytoluidine, and the metals were Al, Cu and Zn. The current-voltage (I-V) plots for these systems were non-linear and capacitance-voltage plots were linear in reverse bias indicating rectification behaviour.
