With highcontent of Ge, however,the crystalline structurechanged and the resistivityof the ï¬lm increased.(Received April 16, 2004; Accepted September 29, 2004)Keywords: zinc oxide, germanium, thin ï¬lm, electrical conductivity, visible light transparency 1.) Zinc oxide has the advantage that it is an abundant andinexpensive compound material in comparison with indiumtin oxide (ITO), which is used as transparent electrode at thepresent time.Someundopedzinc oxideï¬lms showelectrical conduction(resistivity of 4:6 2â5)10 4 10 3 cm).
