Conductivity in SnO2 polycrystalline thick film gas sensors: Tunneling electron transport and oxygen diffusion

Conduction mechanisms in polycrystalline SnO2 thick sensing films were investigated by means of DC electrical resistance during heating-cooling cycles. Samples were maintained at relatively high temperatures in H2 or O2 ambient atmospheres before performing electrical measurements under vacuum or be...
