Diameter-dependent thermodynamic and elastic properties of metallic nanoparticles

Abstract

A simple theoretical model has been proposed to study the diameter-dependent properties of metallic nanoparticles, i.e. Ag , Au , Al , Ni , Pb , Cu and Fe . The diameter-dependent thermodynamic properties includes melting temperature, Debye temperature, evaporation temperature, melting enthapy and melting entropy. The model is also extended to study the diameter-dependent elastic properties including bulk modulus, Young's modulus and thermal expansion coefficient. On comparison with available experimental findings and other theoretical approaches, the results obtained with the present formulation depict a close agreement and demonstrate the validity of the method proposed in the present paper.
