Structural control of CdTe nanostructures. a CdTe film grown on a Bi-coated film. b Bi-assisted CdTe film grown on a Bi-coated film. c Bi-assisted CdTe NWs grown on a Au-coated film at 460 °C. d Bi-assisted CdTe NWs grown on a Au-coated film at 540 °C. e CdTe NWs grown on a Au-coated film. f Average lengths of CdTe NWs grown at different conditions. g TEM images of CdTe NWs. The right-hand image shows a magnified TEM image measured on a single CdTe NW. The upper inset shows the diffraction pattern of the CdTe NW. h EDS measurement of as-grown CdTe NWs
