A Simple Way of Synthesizing Single-Crystalline Semiconducting Copper Sulfide Nanorods by Using Ultrasonication during Template-Assisted Electrodeposition
نویسندگان
چکیده
We demonstrate here the utilization of ultrasonication during template-assisted electrodeposition to synthesize high quality one-dimensional nanostructures. Copper sulfide nanorods were synthesized “sonoelectrochemically” to achieve single-crystal nanorods with predominantly single stoichiometric composition (1.0:1.0 Cu:S). Structural characterization by HRTEM, SAD, EDS reveals that nanorods have fully crystalline hexagonal covellite (CuS) structure, which is topotactically intergrown with minor amounts of nanometer size domains of cubic Cu1.8S. Nanorods in the range of 50-200 nm in diameter were produced and electrically characterized as p-type semiconductors.

Template-free CuO nanorods were synthesized through a three-step chemical method with no water-insoluble materials. The first step included the preparation of a Cu-complex, which was obtained from dipicolinic acid, L-lysine, and copper nitrate. Then, as the second step, the obtained solution was allowed to be relaxed for a week to and formation of some blue single-crystals single crystals, whic...
