Abstract

The $CO_2$ gas responsibility of $SnO_2$ thin films was researched with various annealing temperatures. $SnO_2$ was prepared on n-type Si substrate by RF magnetron sputtering system and annealed in a vacuum condition. The bonding structure of $SnO_2$ was changed from amorphous to crystal structure with increasing the annealing temperature, and the content of oxygen vacancy was researched the highest of the annealed at $60^{\circ}C$. The $SnO_2$ annealed at $60^{\circ}C$ had the characteristics of the highest capacitance. The special properties of $CO_2$ gas responsibility was found at the $SnO_2$ thin film annealed at $60^{\circ}C$ with amorphous structure because of the combination with the oxygen vacancies and $CO_2$ gases changed the resistivity. The amorphous structure enhanced the responsibility at the $SnO_2$ surface and the conductivity of $SnO_2$ thin film.
