The molecular dynamics simulation technique with many-body and semi-empirical potentials was used to calculate the (114) twin-boundary in gold at different temperatures. Relaxations were found on both sides of the interface with the same magnitude and the phenomenon of coalescence was observed near the interface. The interactions of single-, di- and tri-vacancies with twin-interface at 300K on mirror and off-mirror sites were calculated. Off-mirror arrangements were favorable for all vacancy clusters, except for the single-vacancy cluster, which was less repulsive on the mirror site. Vacancy clusters energetically prefer to lie at planes closest to the (114) interface rather than away from it. The effect of temperature on interaction behavior was also calculated.
