In the first part, an UV sensor of zinc oxide wire of 0.5µm~3µm wide and 10 µm long is built with CBD and electron beam lithography technology. The UV response and the I-V characteristics of the sensors are measured and analyzed. In the second part, a graphene resonator is built on a 300 nm gap, at the middle of the zinc oxide wire, covered by a piece of graphene. The result shows measurable resonant frequencies around GHz depending on different graphene configurations. This frequency will be very sensitive to the environment change and provide us a useful tool for sensor application.
