Synthesis and characterization of CdS nanowires — •Jens Böttcher, Marko Burghard, and Klaus Kern — Max-Planck-Institut für Festkörperforschung, Stuttgart

Cadmium sulphide (CdS) nanowires with an average diameter of 30 nm and lenghts of up to 10 µm have been synthesized via a novel solvothermal method that uses a single-source precursor and ethylenediamine as coordinating solvent. Investigations by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission microscopy (HRTEM), thermal gravimetric analysis (TGA), and photoluminescence (PL) studies indicate that the described synthesis approach yields pure, structurally uniform, and single crystalline nanowires. Furthermore, spatially resolved photoconductivity measurements were used to determine the mechanism of photocarrier transport in individual CdS nanowires.
