Oxygen clamps in gold nanowires
arXiv:cond-mat/0509529 · doi:10.1103/PhysRevLett.96.016104
Abstract
We investigate how the insertion of an oxygen atom in an atomically thin gold nanowire can affect its rupture. We find, using ab initio total energy density functional theory calculations, that O atoms when inserted in gold nanowires form not only stable but also very strong bonds, in such a way that they can extract atoms from a stable tip, serving in this way as a clamp that could be used to pull a string of gold atoms.
