Electrical properties of the SnO2-based varistor
(1998-12-01)
The non-linear electrical properties of CoO-doped and Nb205-doped SnO2 ceramics were characterized. X-ray diffraction and scanning electron microscopy indicated that the system is single phase. The electrical conduction ...

Electrical and spectroscopic analysis in nanostructured SnO2: "long-term" resistance drift is due to in-diffusion
(American Institute Of Physics, 2011-11-07)
A model for conductance in n-type non-degenerate semiconductors is proposed and applied to polycrystalline SnO2 used as a gas sensor. Particular attention is devoted to the fundamental mechanism of Schottky barrier formation ...
