摘要

The electron transport process in DNA-doped polypyrrole (PPY) nanocomposite film deposited on tin oxide coated glass by a simple electrodeposition technique is demonstrated here. Optical absorbance spectra clearly exhibited features corresponding to doped PPY nanocomposite film. The I-V characteristics of the films were non-ohmic and showed a significant change when illuminated with light. Photoinduced I-V profiles suggested carrier hopping to be the dominant transport mechanism in the nanocomposite PPY film. The temperature-dependent dc electrical conductivity data showed a crossover from variable-range hopping to thermally activated hopping of electrons with the increase in temperature. The ac electrical transport properties displayed a frequency-independent region below a characteristic frequency of approx 400 kHz, above which the conductivity showed a strong frequency-dependent behaviour.
