What does an (a+c) dislocation core look like in wurtzite GaN ?

Here we present results on the first atomic simulation of the threading (a+c)-mixed dislocation cores in wurtzite GaN. These calculations are based on a modified Stillinger-Weber potential. For this dislocation two core configurations are shown to be stable, one with a complex double 5/6-atoms rings and the other a with 5/7-atom rings structures. The two cores contain neither wrong nor dangling bonds.
