Abstract
Electrophysical properties of nanosized SnO2 layers obtained using PVA as a structural additive in the presence of water and ethanol vapor at room temperature have been investigated. It is established almost the tenfold increase of conductivity of investigated layers in the presence of water vapor and the five times one in the presence of ethanol vapors compared with its value in dry air which is caused by dissociative adsorption of water and ethanol on their surfaces. An abnormal nature of the dark current temperature dependence of tin dioxide layers in the presence of water vapor in the temperature range 40–90 oC is associated with desorption processes on the surface. The obtained results show the possibility of using the investigated layers of tin dioxide for a moisture and ethanol detection at room temperature.
