Fabrication and field emission properties of patterned ZnO arrays
zinc oxide (ZnO) dendritic structures were controlled by pattern technology and their properties were studied. Firstly
patterned zinc oxide (ZnO) thin films were prepared by the use of photolithography on the ITO glass substrate. Patterned dendritic ZnO arrays were successfully synthesized on the ITO covered with patterned ZnO thin film by using a simply electrodeposition approach. Then
the morphology and structure characteristics of as-prepared ZnO nanostructures were characterized by scanning electron microscopy and X-ray diffraction
respectively. Moreover
field emission properties of pattern ZnO arrays were also explored. The results show that the patterned ZnO arrays are circular arrays with the diameter of 330
μ
m
the diameter of average ZnO trunks are 400~500 nm. There are many nametapes on the ZnO trunks. They exhibit good field emission properties with a turn-on field of 2.15 V/
μ
m and a field enhancement factor of 16 109. The patterned ZnO array is a feasible method for improving field emission properties.
