Computer simulations suggest that ultrathin metal wires should develop exotic, non-crystalline stable atomic structures, once their diameter decreases below a critical size of the order of a few atomic spacings. The new structures, whose details depend upon the material and the wire thickness, may be dominated by icosahedral packings. Helical, spiral-structured wires with multi-atom pitches are also predicted. The phenomenon, analogous to the appearance of icosahedral and other non-crystalline…

An atomistic simulation study of cylindrical ultrathin Cu nanowires

In order to understand the structure and properties of cylindrical ultrathin copper nanowires, we have simulated the growth of cylindrical copper nanowires using the steepest descent method, and

Study on the Nanoconfinement-Induced Breaking of Helical Symmetry in Metal Nanowires

Metal atoms confined in finite cylindrical nanopores exhibit helical morphologies because of the high rotational symmetry of confined surfaces and energy minimum of (111) facets. Herein, we present

Electronic and magnetic properties of ultrathin rhodium nanowires

The structures of ultrathin rhodium nanowires are studied using empirical molecular dynamics simulations with a genetic algorithm. Helical multishell cylindrical and pentagonal packing structures are

Formation of pentagonal atomic chains in BCC Fe nanowires

For the first time, we report the formation of pentagonal atomic chains during tensile deformation of ultra thin BCC Fe nanowires. Extensive molecular dynamics simulations have been performed on

Shell structures of sodium nanowires from atomistic simulations

The structural and transport properties of sodium nanowires up to $2.4\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ in diameter are studied using an unbiased genetic algorithm search combined with local

The electronic structure of 4d transition-metal monatomic wires

Monatomic nanowires of the nonmagnetic transition metals Ru, Rh, and Pd have been studied theoretically, using first-principles computational techniques, in order to investigate the possible onset of

Structures and electronic properties of ultrathin titanium nanowires

The structures of free-standing titanium nanowires are studied by using a genetic algorithm with a tight-binding potential. Helical multi-walled cylindrical structures are obtained and pentagonal

Observation of the smallest metal nanotube with a square cross-section.

The spontaneous formation of the smallest possible metal nanotube with a square cross-section during the elongation of silver nanocontacts is reported, indicating that the hollow wire forms because this configuration allows the surface energy to be minimized, and also generates a soft structure capable of absorbing a huge tensile deformation.
