Phys. Rev. Lett. 79, 3455–3458 (1997)Gold Nanobridge Stabilized by Surface StructureReceived 10 March 1997; published in the issue dated 3 November 1997 We formed gold nanowires using electron-beam irradiation in an ultrahigh vacuum electron microscope. The dimensions of these nanowires were 0.8–3 nm in thickness and 5–10 nm in length. The nanowires showed lasting stability. We propose a structure model for a nanowire with a thickness of 2 nm. The model is represented by a hexagonal prism; the surface layer of the prism has a hexagonal-close-packed (hcp) lattice, and the core of the prism has a face-centered-cubic structure. The nanowire is considered to be stabilized by the hcp lattices of the surfaces. © 1997 The American Physical Society URL:
