摘要

We have developed a new and inexpensive method for preparation of ZnO nanostructures (nanorods) for sensor applications. We use hydro-thermal method and fairly low growth temperature of 50°C. As a substrate gallium arsenide and silicon wafers were selected with gold eutectic mixture prepared on their surface. We used deionized water and zinc acetate as an oxygen and zinc precursors, respectively. The eutectic mixture nucleates growth of ZnO nanorods. These structures show sensor behavior when different chemical solvents and gases are applied. Importantly, the so-obtained sensor works at room temperature and heating and processing is not required to reset them to initial resistivity.
