Summary:
In a solid, the electrical conductivity and optical transparency seem to be two contradictory physical properties. Conductive materials are opaque, and transparent solids are electrical insulators. Combinations of these two physical properties in a material make it appropriate for application in many optoelectronic devices. The coincidence of these two properties has been mainly ascribed to point defects in the crystal lattice. In this work, we performed structural, electrical and optical characterization of thin films of one of the most promising transparent conductive oxides Sn1-xO2 Nbx . The films were grown on glass substrates by RF magnetron sputtering technique. As the deposition power was varied, it was found that the electrical conductivity of the films increased with increasing power deposition, and they showed a preferential growth in the (200) direction. All films exhibited optical transmittance in the visible range larger than 80%.
