Molecular dynamics studies of palladium

Equilibrium bulk properties of Pd are examined using molecular dynamics technique based on the embedded atom potential. We calculate the total energy and the lattice parameter as a function of temperature. Melting temperature is determined from the discontinuous transition in the energy and lattice parameter. Specific heat and linear coefficient of thermal expansion are calculated from the energy and lattice parameters respectively and results show good agreement with experimental values. Finally the mean square displacements of thermal expansion are calculated form the energy and lattice parameters respectively and results show good agreement with the experimental values. Finally the mean square displacements of the atoms in bulk Pd are compared with the mean square displacements on the three low-index faces (100), (110) and (III). (author)
