Abstract
Electrical and optical characterization of vacuum deposited magnesium phthalocyanine thin films and their effect on substrate temperature an d post-deposition annealing have been studied. Thermal activation ener gy in the intrinsic region is found to increase in the temperature ran ge 323-473 K. Substrate temperature in the range 323-473 K increases t he band gap from 2.56 to 2.80 eV while post-deposition annealing has n ot much effect.
