Electrochemical fabrication of ultralow noise metallic nanowires with hcp crystalline lattice

摘要: We experimentally demonstrate that low-frequency electrical noise in silver nanowires is heavily suppressed when the crystal structure of hexagonal closed pack (hcp) rather than face centered cubic (fcc). Using a low-potential electrochemical method we have grown single crystalline with hcp structure, which at room temperature two to six orders magnitude lower conventional fcc same diameter. suggest motion dislocations probably primary source metallic nanowires, strongly diminished crystals.
