Abstract

The electrical properties of compressed nanocrystalline tin (IV) oxide were studied. It was observed that the room temperature electrical resistance of nanocrystalline SnO₂ samples increased with increasing partial pressure of oxygen. In addition, when there is a sudden change in the oxygen partial pressure, a short pulse of spontaneous electromotive force of the millivolt order can be detected. This new finding has the potential application of leakage detection in vacuum systems or pressure vessels.
