Cross-section HRTEM images of AlN NWs. a Interface area between an AlN NW and the Si (111) substrate. b Image of an NW and the film connecting to it. c Magnified image of the area in the white circle in (b). The white arrows indicate the boundary between the AlN NW and the film, and the nearby distorted lattice in the AlN NW can also be clearly observed. The red circles highlight the dislocations in the films
