Physical properties of transparent and conductingindium tin oxide (ITO) thin films grown byradiofrequency (RF) magnetron sputtering are studiedsystematically by changing deposition time. The X-raydiffraction (XRD) data indicate polycrystalline thin filmswith grain orientations predominantly along the (2 2 2) and(4 0 0) directions. From atomic force microscopy (AFM) itis found that by increasing the deposition time, theroughness of the film increases. Scanning electron microscopy(SEM) images show a network of a high-porosityinterconnected nanoparticles, which approximately have apore size ranging between 20 and 30 nm. Optical measurementssuggest an average transmission of 80 % for theITO films. Sheet resistances are investigated using fourpointprobes, which imply that by increasing the filmthickness the resistivities of the films decrease to2.43 x 10(-5) Ω cm.
