Abstract

Atomic structures of 60° dislocations were calculated in bulk Si and Ge ,and at Ge/Si interfaces, using energy minimization techniques. An empirical three body potential developed by Stillinger-Weber was used for Si ,and the same potential with modified parameters was used for Ge. Two different configurations of a 60° dislocation (shuffle and glide) were compared. Energetics of a 60° dislocation in shuffle configuration in bulk Si and Ge , and at Ge/Si interfaces are discussed.
