Transport coefficients of liquid transition metals: A computer simulation study using the embedded atom model
Using the Voter and Chen version of the embedded atom model, we carried out molecular dynamics simulations to compute the diffusion constants and shear viscosities of liquid Pd, Pt, Cu, Ag, and Au as representative of single-particle and collective dynamic properties, respectively. The generally good agreement between the calculated values and available experimental data is evidence that the Voter and Chen embedded atom model allows a reliable description of the dynamic properties of liquid transition metals in spite of being derived from solid-state data and the properties of the diatomic molecule. The discrepancy between the reported experimental diffusion constant of liquid Cu and the values calculated in this work, together with the consistency of these latter, suggests that the reported experimental value may be in error.
