PROJECT TITLE :

In-Situ Hydrothermal Synthesis of Zinc Oxide Nanostructures Using Microheaters

ABSTRACT:

A technique for in-situ hydrothermal synthesis of transversely suspended zinc oxide nanowires (ZnO NWs) using microfabricated heaters is presented. A number of issues regarding seed layer preparation, directed alignment, native heating management, and therefore the concentration of the synthesis solution are investigated for this method. It's shown that ZnO NWs will be synthesized and aligned from the ZnO seed surface to bridge 2 adjacent microheater parts. Moreover, hybrid ZnO nanotubes and nanorods also are synthesized by controlling the concentration of the synthesis resolution utilized. The crystalline structure of synthesized ZnO nanostructures are characterised by the transmission electron microscope and selective area electron diffraction. Finally, ZnO NW devices based on proposed microheater synthesis approach are characterised for UV photoresponsivity demonstrating the potential of this approach to handle practical device applications.
