Semiconductor nanorods: Cu, Zn, and Cd chalcogenides

Semiconductor nanorods have been synthesized by the use of surfactants. The nanorods of CuS, ZnS, CdS, CuSe, ZnSe, and CdSe have diameters in the 5–150 nm range and exhibit high aspect ratios, with lengths of up to several microns. By using a high surfactant concentration, nanotube‐like structures of CdS and CdSe with high aspect ratios are obtained. All the chalcogenide nanostructures possess hexagonal structures, independent of the structures of the stable phases of the materials.
