Abstract :
Nanotetrapod zinc oxide (ZnO) thin films have been deposited by thermal chemical vapor deposition (TCVD) technique. The films were deposited at 700°C and 800°C to study the temperature effect of physical properties of the nanotetrapod ZnO thin films. From XRD result shows the highest peak can observed from sample 700°C at (002) orientation. It was found that the size of nanotetrapod increased with increased of deposition temperature. The energy dispersive X-ray spectrometer (EDX) spectrum shows that the grown product contains zinc and oxygen only. At 800°C show the minimum of resistivity for the thin film which is 1.10 ohm. cm. Photoluminescence measurement shows a sharp peak ultraviolet emission at 380 nm and high intensity visible peak at 700°C because of defect due to oxygen vacancy and crystallization of ZnO nanotetrapod.
