Relation between the size dependences of the melting and crystallization temperatures of metallic nanoparticles
Abstract
The relation between the melting and crystallization temperatures of metallic nanoparticles is studied using a thermodynamic approach. The size dependences of the melting temperatures of tin and copper nanoparticles are calculated with allowance for the corresponding size dependences of the surface tensions of the solid and liquid phases and the interfacial tension. The size dependences of the crystallization temperature are obtained with allowance for the effective surface layer (skin layer) that forms in melting of a nanoparticle.
