Controlled Morphology of Electrochemically Deposited CuSCN by Variation of Applied Bias Voltage

CuSCN is a p-type semiconductor essentially used in semiconductor sensitized solar cells for scavenging the photogenerated holes. Here we report, cathodic electrodeposition of CuSCN using NaSCN and Cu2+. Control over the film morphology is found to be highly dependent on the applied potential. One-dimensional rod like morphology with a strong (003) orientation is obtained under lower applied potential. Under higher applied potential the morphology changes to a more granular type. Films are structurally characterized by x-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM) with small angle electron diffraction (SAED).
