Abstract
The atomic structure of a Σ=11 tilt grain boundary in gold was simulated by the molecular dynamic techninue using the Morse potential. The simulated structure is compared with the lattice image of a Σ=11 boundary in gold observed by high resolution electron microscopy. The local density of states of phonons was calculated by the recursion method for atoms near the boundary plane. It was found that the resonant mode with a large amplitude occurs with atoms at the boundary plane.Keywords
