摘要：

In the present work, we have investigated the relative energy of different core configurations of the 30 degrees Shockley partial dislocation in wurtzite GaN. By using a modified Stillinger-Weber potential, we have carried out large scale calculations on models containing many thousands of atoms. Both glide and shuffle configurations have been considered within the two core polarities (Ga, N). Similarly to what was reported for conventional semiconductors, our calculations showed that the reconstructed glide configurations are energetically favoured over the shuffle ones.
