A formation mechanism for so-called nanotube defects in GaN is proposed. It is shown that two related types of defects are formed: nanotubes and pinholes. Both start with V shaped facets on {l_brace}10{ovr 1}1{r_brace} polar planes. Slow growth rate on these polar planes and impurity poisoning of growth steps are suggested as being responsible for initiation of these defects. {copyright} {ital 1997} {ital The American Physical Society}
