yes and no. There are cases in which relatively small supercells describe well the defect (i.e. the interaction of the defect with its periodic replica is small) but do not describe well the underlying crystal structure if one uses the Gama point only. In those cases, using k-points makes sense. Paolo -- Paolo Giannozzi, Democritos and University of Udine, Italy
