Abstract<\/h3>\n\n\n\n

A thermodynamically consistent phase field formulation was developed to describe what has been historically known as the premelted surface layer in Sn nanoparticles. Two interfacial phases were identified: 1) a disordered interfacial phase, i.e., the experimentally observed premelted surface layer; and 2) an ordered surficial phase displaying a remnant degree of order in fully melted particles. A volumetric partially disordered particle core is predicted to exist for small particle sizes, r<7 nm. Four regimes of behavior are discussed: a) the classic premelting regime<\/em>, for r>20 nm, in which the surface of the particle forms a liquid shell at temperatures below melting with clear delineation between the solid core and the premelted surficial liquid shell, as traditionally expected; b) the transition regime<\/em>, for 5<r<20 nm, in which the volumetric chemical potential and interfacial forces balance each other out; c) the disordered volume phase regime<\/em>, for r<5 nm, in which a disordered interphase dominates the thermodynamic equilibrium of the system resulting in a partially crystalline core, and d) the mesoscale regime<\/em>, in which the nanoparticles are no longer considered crystalline and experience an associated decrease in latent heat.<\/p>\n\n\n\n
