Resumen:
The distribution of oxygen vacancies in metal oxide nanograins was modeled, considering the possibility of oxygen in- and out-diffusion, in a field-assisted and thermionic emission conduction model. Implications in electrical responses of SnO2 to oxygen concentration and temperature variations will be discussed and compared to an oxygen-free tin semiconducting compound.
