We investigate the structural evolution on melting of Gold nanoparticle due to heat treatment from room temperature up to slightly above melting point. The evolution is followed using Molecular Dynamics (MD) simulation. Structure factor and pair distribution function calculation indicated that the system is melted at the end of simulation. Common Neighbour Analysis (CNA) method shows the local lattice structure transformation confirming phase transition.
