Aluminum nitride nanotubes | SpringerLink

An AlN nanotube (AlNNT) was theoretically predicted in 2003. In comparison with the carbon nanotubes, the AlNNTs are wide-band-gap nanostructures with high reactivity, high thermal stability and sharp electronic sensitivity toward some chemicals. The B3LYP predicts an HOMO–LUMO gap of 3.74–4.27 eV for zigzag AlNNTs, while the experimental bad gap of bulk AlN is about 6.28 eV.
