摘要：

Ac spectroscopic measurements in the range of 10 kHz and 1 MHz are performed on sublimed MoOPc films on ITO glass substrates. The conduction mechanism is believed to be due to hopping of carriers. Using the Cole-Cole relaxation model, the mean dielectric relaxation time is found to be 942-mu-s at room temperature. The effect of voltage cycling and annealing is studied by optical absorption; the annealed films show lower absorption while the Davydov splittings are absent from the spectra for the voltage-cycled samples.
