Aligned and open-ended nanotube structures, methods for making the same, and devices including open-ended nanotubes. An aligned and open-ended nanotube structure which is free of catalyst particles at top ends, the aligned and open-ended nanotube structure having an uneven open-end height with local protruding portions. A method of opening an end of a nanotube including a catalyst particle including sputter etching the nanotube to remove an amorphous layer, bend the nanotube to one side, open a hole in the nanotube, and cause detachment of the catalyst particle.
