Abstract
Undoped and antimony-doped tin oxide (ATO) thin films were prepared by sol-gel process in the solution of metal salts of tin (II) chloride dehydrate and antimony tri-chloride. The microstructure of the thin films was analyzed by scanning electron microscope (SEM) and X-ray diffraction (XRD). Compared with undoped tin oxide, doped antimony tin oxide films coated glass substrate were homogeneous in composition and morphology after being sintered at different temperatures. Electrical behavior of the doped films was discussed in terms of sheet resistance measured by four point probe. From the experimental data, the sheet resistance of the films could be as low as 100-200Ω/□
