VIBRATIONAL-SPECTRA OF SOME BINARY SEMICONDUCTING OXIDE GLASSES

The frequency-dependent complex relative permittivities of binary semiconducting V2O5-P2O5 glasses containing various amounts of vanadium have been measured at ambient temperature in the infrared region by power reflection spectroscopy. The measured values of the static constant, ε0, and high frequency constant, εx, are used to calculate the small polaron binding energy, Wp and the activation energy for conduction in the vanadium phosphate glasses, and comparisons are made with published data. © 1990 Chapman and Hall Ltd.
