摘      要：The surface photovoltage(SPV)mechanism of a silicon nanoporous pillar array(Si-NPA)is investigated by using SPV spectroscopy in different external electric *** comparisons with the SPV spectrum of single crystal silicon(sc-Si),the silicon nano-crystallite(nc-Si)/SiO_(x) nanostructure of Si-NPA is proved to be capable of producing obvious SPV in the wavelength range 300–580 *** SPV for the sc-Si layer and the nc-Si/SiO_(x) nanostructure has shown certain contrary characters in different external electric *** analysis,the localized states in the amorphous SiO_(x) matrix are believed to dominate the SPV for the nc-Si/SiO_(x) nanostructure.
