Abstract The effects of wire diameter and grain size on the melting point of Ni nanowires with and without oxide capping were systematically examined. It was found that, for uncapped Ni nanowires, the melting point drops monotonically with grain size and also with the nanowire diameter; for oxide-capped Ni nanowires, the melting point rises when the nanowire diameter is decreased. Findings indicate that: (i) the reduced cohesive energy of under-coordinated atoms at the surface skin or grain… CONTINUE READING
