In this work we studied deposition conditions by RF sputtering of ternary oxides of Cd and Sn, starting from Cd2SnO4 target and varying substrate temperature, sputtering power and deposition gas (from inert Ar to oxidizing 50% Ar–50% O2 atmosphere). The aim of this study was to obtain thin films for use as Transparent Conducting Oxide (TCO). TCOs are oxides that couples low sheet resistance and high transparency that find application in many fields like solar cells, light emitting diodes and transparent thin film transistors.Thin films functional properties were characterised by means of sheet resistance and transmittance measurements in the visible region, and film composition and structure were investigated by total reflection X ray fluorescence and glancing incidence X ray diffraction. Morphology was studied by Atomic Force Microscopy and Scanning Electron Microscope and showed very smooth surface …
