      abstract     = {The meandering of v-shaped defects in GaN(0001) epitaxial
                      layers is investigated by cross-sectional scanning tunneling
                      microscopy. The spatial position of v-shaped defects is
                      mapped on (101¯0) cleavage planes using a dopant
                      modulation, which traces the overgrown growth front. Strong
                      lateral displacements of the apex of the v-shaped defects
                      are observed. The lateral displacements are suggested to be
                      induced by the meandering of threading dislocations present
                      in the v-shaped defects. The meandering of the dislocation
                      is attributed to interactions with inhomogeneous strain
