Long hollow nanopipes in epitaxial GaN thin films have been found to evolve under electron irradiation into the so-called bamboolike structure. The transition from the single nanopipe into a chain of pinholes is described in terms of morphological instability driven by the differences in the surface energy of crystallographic planes.
