Abstract

The electrical transport behaviour of ferrocene mixed polymethylmethacrylate (PMMA) films (approximately 20 microns in thickness) deposited by the isothermal immersion technique has been studied in the temperature range of 333-373 K and field from (2.0-4.0)×10⁴ volts/cm. It has been found that at higher fields and temperatures, the observed conduction behaviour could be consistently described by the Richardson-Schottky emission. Increase in current due to doping has been attributed the formation of charge transfer complexes. The dopant molecules acts as an additional trapping centre and provide a link between polymer molecules in the amorphous region leading to the formation of a charge transfer complex
