The electronic properties of disorder/order phase transition in C 60 thin films were studied using surface photovoltage (SPV) spectroscopy at 120-300 k. The thin films were deposited on a substrate of optical glass predeposited with a silver layer using vacuum deposition technique. The atomic force microscopy (AFM) was used to study the morphology of the front surface of the films. The results show that the energy position of the thresholds exhibited nonmonotonic behavior with a mirror symmetry.
