Classical numerical simulations, which were based upon a micro-crystal of about 20000 atoms, were used to predict the structures and energies of intersection of (a/2)<110> edge dislocations in diamond cubic materials. It was found that the most compact of the 3 intersections was preferred. It was noted that photoluminescence techniques offered a possible means for detecting and characterizing these intersections.
