(a) Correlation between the segregation energy of vacancies with the minimum atomic volume site and interstitials with the maximum atomic volume site, relative to the atomic volume of a site in bulk Cu, at the four GBs considered. (b) Correlation between the migration barrier of mono-interstitials and the distance between maximum atomic volume sites in the four GBs (the points for the two tilt GBs overlap at the shortest distance).
