Large-scale fabrication and characterization of Cd-doped ZnO nanocantilever arrays

We demonstrate bulk synthesis of highly crystalline Cd-doped ZnO nanocantilever arrays (CZNAs) using Cd and Zn powders at 600 °C, which is characterized via scanning electron microscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy, selected area electron diffraction, and high resolution TEM. The results show that the as-prepared CZNAs have diameters of about 15-50 nm, and lengths up to 400 nm and the corresponding process of growth is suggested for conventional vapor solid mechanism.
