MOLECULAR-DYNAMICS SIMULATION OF PLATINUM PARTICLES BETWEEN GRAPHITE WALLS

We report preliminary molecular dynamics simulations results for plati num atoms confined between two parallel graphite surfaces. The system shows phase transition characteristics corresponding to a second order transition. Significant structural changes are also observed in the r ange of temperature studied. We have also investigated the effects of two different Pt-wall interaction potentials: the 9-3 form suggested b y Crowell and the 10-4 form originally proposed by Steele. The results show that the two systems have rather different structural characteri stics but similar thermodynamic behaviour.
