Abstract
The size dependences of the temperature and heat of melting of transition metal nanoclusters (Ni, Au, Cu, Ag) have been investigated using the isothermal molecular dynamics and tight-binding potential. It has been shown that the heat of melting Λ for nanoclusters approximately 1 nm in size should be two to three times less than the macroscopic heat of melting Λ(∞). It has been found that the heat of melting Λ decreases with a decrease in the size of nanoclusters and, in some approximation, depends linearly on their inverse radius R −1.
