Abstract
Electrical conductivity and photoconductivity measurements were carried out on semiconducting vanadium oxide nanowire networks synthesized through the polycondensation of vanadic acid. The temperature-dependent conductivity was described well by Mott's optical multiphonon assisted hopping model at high temperatures and by the variable-range hopping mechanism at low temperatures. The photoconductivity showed a weak temperature dependence. Besides, quasipersistent photocurrent with a single-exponential decay behavior was observed right after switching off the light and was explained in terms of the random local-potential fluctuation model.
