Piezoelectric effect of quaic-nanotetrapods ZnO nanostructure

摘要

Quaic-nanotetrapods ZnO nanostructure were fabricated by a simple chemical vapour deposition method. The morphologies, crystalline qualities and optical characteristics of the quaic-nanotetrapods ZnO nanotetrapods were investigated by scanning electron microscopy(SEM), X-ray diffraction (XRD) and photoluminescence (PL) analytic technology, respectively. A piezoelectric nanogenerator based on the ZnO nanotetrapods was fabricated by a simple technique. And the energy harvesting ability is studied by experimental characterization methods and theoretical calculations.
