Abstract: The Monte-Carlo lattice method is used to search for the surface structure of crystalline copper nanowires of various orientations. Fragmentation of 3,3 nm thick wires into individual spherical nanoparticles is observed. When a nanowire with an initial orientation along the  crystallographic axis is rotated, its surface energy increases monotonically to a certain value of the angle of rotation, with a further decrease with orientation along the  axis. A dependence of the surface energy on the nanowire’s diameter was not revealed.
Keywords: surface, Monte Carlo method, tight-binding potential, crystal lattice, nanowire, Rayleigh-Plato instability, fragmentation.
