Abstract
Total energy calculations performed to study the migration of silicon self-interstitials reveal a great complexity of migration paths. and each migrate along more than one path and different paths from each other. Some paths involve interchange with bulk atoms. Electron-assisted transport occurs for the stable tetrahedral site in all directions. has several almost-degenerate lowest-energy configurations. The lowest is the "exchange" configuration which also has the possibility of being negative ().
