Abstract
Impedance studies were conducted on spray deposited Cu doped SnO2 thin films. Rietveld analysis provided evidence of non-existence of any other phase due to doping. Controlled injection of ethanol vapor was done to study the surface activity of these films at different temperatures. The cole-cole plots of ethanol absorbed films to that of unexposed thin films were constructed at different temperatures and compared. The studies reveal that the electron scattering process was homogeneous in nature and the film had a narrow relaxation time. Levenberg-Marquardt algorithm with unweighted function was used for theoretical fitting of the cole-cole plots that revealed the weakening of the Fermi pinning level.
