Title: Electrical transport in heterojunction polymer films

Conducting polymer based heterojunction films were synthesized using spin coating technique. Current – Voltage (I-V) characteristics of the films were investigated before and after annealing up to 80°C. It was found that Schottky emission is main charge transfer mechanism observed for the films. Annealing strongly influences the I-V characteristics suggesting a strong change in internal morphology due to thermally assisted phase separation. The relative dielectric permittivity was calculated which depends on the applied field as well as annealing temperature.
