Electrochemical growth and characterization of CdTe nanorod arrays

The straight one-dimensional CdTe nanorod arrays on indium tin oxide coated glass substrate with high purity have been synthesized using a rapid and convenient electrodeposition method. The electrodeposited thin films were studied and investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), and UV–vis absorption spectroscopy. The structural and optical studies revealed that films are possess sphalerite phase. The device based on the aligned array-on-ITO configuration demonstrates excellent photoresponse to the visible light, which is ascribed to the large absorption coefficient of the material and also suggests good electronic structure quality of the nanorods.
