摘要: The photoresponses of SnO2 nanobelts grown in situ among interdigital electrodes on silicon substrates were investigated under ultraviolet (UV) light and green laser illumination. current increased to ~140?nA vacuum irradiation with a power 35.1?mW. Under UV illumination, however, the source?drain ~80??A air up ~900??A vacuum, respectively. photoresponse was result electron transition from valence band conduction band, while dependent oxygen pressure, ambient temperature defect levels.
