Grain boundary energy and grain growth in Al films: Comparison of experiments and simulations

Relative free energies of (111) tilt boundaries in 1.7-mu m-thick A1 films were compared with boundary enthalpies obtained via molecular dynamics simulations. Grain growth studies in 25 and 100-nm-thick A1 films were compared with simulations. The sources of the differences between experimental and simulational results are discussed.
