Bending Properties of ZnO Nanorod using Nano-Manipulator

나노조작기를 이용한 ZnO 나노막대 굽힘 물성 평가

The bending test of an individual ZnO nanorod was performed with a nano-manipulator and a force sensor inside the scanning electron microscope (SEM), and the bending properties of ZnO nanorod were also discussed. The ZnO nanorod used in this experiment was fabricated by means of solution base process. The force sensor used for bending test of ZnO nanorod was typed with cantilever. The force sensor was mounted on the nano-manipulator. The nano-manipulator was controlled and manipulated by a personal computer. The each end of an individual ZnO nanorod was attached on the rigid support and the tip of the force sensor with an electron beam exposure, and then the bending test was carried out by controlling of the nano-manipulator. The bending modulus of a ZnO nanorod was calculated at 69.35GPa after the bending test.
