HRTEM images of ultrathin (15 nm) ZnO nanowire array. (a) Low-magnification image of ZnO NWs synthesized by electrochemical deposition. (b) High-resolution TEM image of 15-nm diameter and  crystal plane. (c) TEM image of lattice fringes suggesting the c-axis growth direction and spacing of 0.58 nm in the adjacent lattice planes. (d) SAED diffraction pattern indicating the polycrystalline nature of grown ultrathin ZnO NW array.
