摘要

Photoconductivity spectra measurement of polymers at x-ray energies around the Zn and Co K edges,shows obvious x-ray absorption fine structure oscillations.The photoconductivity spectra obtained for gapped and sandwiched electrode geometric samples,indicate that the shape of photoconductivity spectrum depends on the electrode configuration of the samples.The thickness of the conduction layer can be estimated from the photoconductivity spectrum.
