Abstract
Electrical characteristics of Ag-PS interfaces under ambient humidity were investigated. The humidity-voltaic effect, i.e. the generation of open-circ uit voltage in Ag-PS interface in humid atmosphere (up to 200 mV at 90% rel ative humidity) is discovered. Humidity-stimulated voltage generation is ma inly caused by hydrogen component of water-vapour of ambient. The possible mechanism related with H-stimulated generation of voltage in Ag-PS interfac e is suggested. (C) 2001 Elsevier Science B.V. All rights reserved.
