Abstract

In this paper we present electron microscopy results near and below the melting temperature, both in dark field and high resolution mode, of lead nanoparticles embedded in a dielectric matrix of amorphous SiOx. Three different size dependent regimes are distinguished. Indications of solid particles rotations as well as of a new phenomenon amenable to spontaneous solid-liquid phase fluctuations will be briefly discussed.

13 - The calculation was performed under the assumption of spherical particles (as confirmed by DF and HREM data) and of a relatively not too strong perturbation at RT due to the presence of the matrix instead of the vapour. It was checked in any case that variations up to 8% in the free energies due to such perturbation do not change the main features of the curves in fig 6.Google Scholar
