The effects of SiO₂ passivation on tin monoxide (SnO) semiconductor was investigated. In X-ray photoelectron spectroscopy studies revealed that the tail-state above valence band maximum was clearly detected in SiO₂- capped SnO film which may improve the p-type conductivity. As a result, the resulting SnO thin-film transistors show enhanced electrical properties.
