Cyclic Voltammetry. The results indicated that one-dimensional(1D) nanopillars were prepared by low concentration of electrolyte
whereas two-dimensional(2D) nanodisks with compact hexagonal were obtainted by high concention of electrolyte. UV-Vis spectroscopy revealed that the transmittance of ZnO nanopillars and nanodisks were more than 85% at the range of 400~900 nm
RTS-8 analysis indicated that sheet resistances of ZnO thin films are about 14.5 /□
Cyclic Voltammetry analysis indicated significant differences of the potentials of oxidation and reduction between two kinds of morphology
