Abstract

Transparent conducting thin films of antimony-doped tin oxide have been deposited by the sol-gel dip-coating (SGDC) method. Electrical properties are analyzed, and resistivity, Hall mobility, type and nunber of carriers measured as a function of the antimony doping. Optical properties are investigated through the spectral transmision and reflection of the layers. The nature of the forbidden band and the width of the gap are determined. Optical and electrical properties are compared with results obtaned on Sb:SnO 2 thin films elaborated by other methods such as chemical vapour deposition, sputtering and pyrolysis, and specific properties of the SGDC material are outlined.

Abstract

The electrical properties of Sb-doped SnO2 films prepared by the sol-gel dip-coating method have been investigated. The X-ray photoelectron spectroscopy (XPS) technique was utilized to determine the actual Sb content in the layers. This content was found to be lower than that expected from the starting solution composition value. The behaviour of the resistivity of the films as a function of this actual doping appeared quite different from that observed by other authors using other deposition methods. As the Sb content in SnO2 increases, the evolution in the distribution of the Sb5+ and Sb3+ components in the XPS spectra has been analyzed. The results are discussed in relation to the conductivity and the coloration of the films.

Abstract

Starting from alkoxides prepared in the laboratory, undoped and Sb-doped tin dioxide (SnO2) thin films have been deposited using the sol-gel dip-coating method. These layers have been charaterized in relation to the environmental conditions during the pulling phase of the process. Among other parameters, the relative humidity ratio in the dip-coating apparatus has been found to be a key factor, for the morphology of the films as well as for the introduction of Sb-doping atoms. Characterization has been carried out by scanning electron microscopy, high resolution transmission electron microscopy and electron spectroscopy for chemical analysis.
