Highly conducting and transparent gallium doped zinc oxide (GZO) thin films had been deposited by r.f. magnetron sputtering method on glass substrates. The dependence of GZO films crystal and conducting properties on argon gas pressure was investigated by X-ray diffraction (XRD)
atomic force microscopy (AFM) and four point probe methods. The obtained GZO films were polycrystalline with a hexagonal wurtzite structure and preferentially oriented in the (002) crystallographic direction. As argon gas pressure increased
the sheet resistance and resistivity both increased with the lowest value of 17.6 /□ and 7.310
-4
cm
respectively. In addition
the transmittance of the GZO films in the visible range was over 90%.
