Abstract

In the process of molecular dynamics simulation studies of gold nanowires an interesting structure is discovered. This is a finite double-wall nanowire with a large empty core similar to single-wall and double-wall carbon nanotubes. The structure of the 16-10 gold nanotube is studied at the room temperature. An investigation of the high-temperature stability has also been carried out. An unusual inward evaporation of atoms from cylindrical liquid walls is found at T>= 1200 K.
