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
