Morphological Evolution of a Fully Faceted Grain Boundary D.L. Medlin and G. Lucadamo Thin Film and Interface Science Department Organization 8721 Mail Stop 9161 Sandia National Laboratories Livermore, CA 94551, USA ABSTRACT We examine the morphological evolution of faceted grain boundaries in gold during annealing. Experiments were performed on oriented gold films composed of two Σ=3 related orientation variants. The boundaries between these variants initially possess a high density of finely spaced (
