Variation of photovoltage spectra for SnO_2/PS/Si during prior-and post-adsorption

Abstract

制备了二氧化锡/ 多孔硅/ 硅(SnO2/PS/SI) 异质结构样品,在不同温度下,分别测量样品吸附氢气、液化石油气前后的光生电压谱。结合X 光电子能谱(XPS) 测量结果,分析了光生电压谱变化的机理SnO 2/PS/Si heterojunction structure samples are fabricated.The photovoltage spectra of the samples during prior-and post-adsorption of H 2 or liquified petroleum at different temperature are measured.In combination with the results of XPS measurement,analysis on the variation mechanism of the photovoltage spectra is made.福建省自然科学基
