“…The droplets maintained their high activity to absorb Ag, Zn, and O vapors during the growth process, thereby resulting in continuous elongation of coaxial nanocables. As Zn and O were exhausted in the droplet after the reaction was finished, Ag was separated from ZnO during the slow cooling process [ 32 ]; a regular polyhedron shape of Ag crystal was finally formed at the tip because of the minimization of the surface energy [ 33 ].

Ag/ZnO and Cu/ZnO coaxial nanocables were fabricated using AgNO3 or copper foil as source materials by the vapor-liquid-solid process. The coaxial nanocables consist of a crystalline metallic Ag or Cu core and a semiconductor ZnO shell. The evolution of the Ag/ZnO products having different morphologies was investigated by stopping the heating at different temperatures. The diameters of the Ag/ZnO nanocables and the Ag cores could be modulated by changing Ag ratio in the source. The electrical characteristics of the Ag/ZnO contact and the influence of annealing reveal a Schottky diode behavior for a single Ag/ZnO nanocable device. The nanocables with uniform shape and controlled size are expected to provide a new choice in various applications of biological detection, nanothermometer, and photocatalysis.
