Özet
The degenerate SnO2thin films were deposited on n-type Si substrates by using the magnetron sputtering system. The conductivity and Hall effect measurements of the films were carried out as a function of temperature. The measured temperature dependent conductivity of SnO2has been analyzed using a comprehensive conductivity model including both the electron-electron scattering and the weak localizations effects. The characteristic parameters describing the conductivity such as the electron-electron scattering coefficient and the weak localization coefficient were determined both experimentally and theoretically, and their values were also discussed within the model describing the conductivity in degenerate SnO2films with n > 1019 cm−3.
