To develop a structure-kinetic property mapping for grain boundaries requires an understanding of their energy landscapes, i.e. the energy basins and nearby saddle points separating adjacent structures. We implement the activation-relaxation technique to obtain a first view of grain boundary energy landscapes for the Sigma 5 (130), Sigma 5 (210) and Sigma 3 (111) grain boundaries in copper. The energy landscapes of these boundaries are very different, which supports a focus on energy landscapes, rather than absolute boundary energy, to understand boundary properties.
