Abstract
Undoped and Sb-doped SnO 2 films ∼100 nm thick have been deposited by electron beam evaporation from bulk samples prepared using sintering technique. Either undoped or Sb-doped SnO 2 films are nearly amorphous, resistive and transparent. With increasing Sb content, the resistivity slightly decreases and then increases with further addition of Sb, which acts as donor and/or acceptor impurity atom in the SnO 2 lattice, respectively. Besides, the doping of Sb inside the SnO 2 lattice was associated with the increase in the film transmission at solar maximum wavelength and the width of optical band gap; which were interpreted in terms of the interaction between the two oxidation states of antimony, Sb 3+ and Sb 5+ and the increase of atomic bond energy, respectively. Moreover, the addition of Sb to the SnO 2 lattice has proved to affect significantly on the refractive index, the extinction coefficient, concentration of free carriers, dielectric constant, electric carrier susceptibility and Mott's parameters, which have been explained and correlated to the film microstructure change.
