Abstract

(Delta) over bar*, and the melting temperature significantly increases with increasing (Delta) over bar. The results for a nanovoid are compared with the melting/solidification of a nanoparticle, for which the melting temperatures, in contrast, are much lower than theta(e). A linear dependency of the melting temperatures with the inverse of the void radius is shown. The present study shows an unexplored way to control the melting from nanovoids by controlling the void size and the width and energy of the surface. Published by AIP Publishing.
