1. GBs in Cu at 1293 K obtained with full approximation of the groove profiles. Due to the Σ9→Σ3+Σ3 dissociation, the value for two (100)Σ3CSL facets is shown instead of (010)Σ9CSL facet. Open circles represent the GB energy σGB for various facets measured with the aid of AFM. The rings mark the values (σGB / σsur)=.
