Growth of CuInSe2 nanowire arrays by pulse electrodeposition with an electrolyte at varying temperatures

We prepared CuInSe₂ nanowire (NW) arrays in an electrolyte at temperatures ranging from 272 K to 318 K by using pulse electrodeposition techniques and an anodized aluminum oxide template. We photographed the detailed microstructures of CuInSe₂ nanowire arrays with high-resolution transmission electron microscopy (HRTEM); the images showed the polycrystalline nature of the CuInSe₂ nanowires made in electrolyte at a temperature of 318 K. The results of X-ray diffraction and scanning electron microscopy showed that the electrodeposition temperature constrained the CuInSe₂ NW nucleation mechanism.
