Packaging of ZnO nanobelts as nanosensors: Synthesis, Alignment and Characterization

One-dimensional ZnO nanobelt exhibits unique properties which makes it a perfect candidate for sensors in various applications. In this paper, synthesis of ZnO nanobelts is described. Design and fabrication of electrodes are presented. Alignment of nanobelts, which is assisted by the optimized designed electrode, is discussed. Dramatic improvement of the contact resistance is found after the sample is annealed at 500degC for 1 min. This work lays the foundation for further fabrication, fictionalization and packaging of ZnO nanobelt based sensors
