Shape controlled process of nanostructure has been studied for decades because not only it’s a topic that contains various fascinating scientific issues, but also it’s a technique that has many attractive advantage. Usually the intrinsic properties of materials are heavily depended on their morphology, as a results, shape controlled process is a technique that allows to tune the physical, chemical properties. As an example, ZnO is one of the most suitable materials to quenching the electron because ZnO normally has high electron mobility. Moreover if tuning ZnO to have one dimension morphology such as nanowire, we can enhance the electron mobility of ZnO. In this trend, ZnO has been controlled to many different shapes, depending on the mechanical method or chemical etching, mainly by acid etching. Therefore, we propose a new method to control ZnO in various shapes with easy washing process, relatively easy control of etching rate by using transition metal. |
