Abstract

Vacuum evaporated gallium phthalocyanine chloride thin films were prepared at room temperature. Post evaporation annealing was done in air at temperatures 348 K, 398 K, 448 K and 498 K. The electrical conductivities of these films were studied and thermal activation energies were calculated from the Arrhenius plots. A decrease in activation energy was observed with increasing annealing temperature.

Keywords
