title: Kekulé count in capped zigzag boron-nitride nanotubes.
abstract: Hemi-B16N16 capped zigzag boron-nitride nanotube is introduced, and its Kekulé count is studied. With a bond-allocating and coding scheme, recurrence formulas are established as well as for the case of a hemi-B36N36 capped zigzag nanotube. Numerical results reveal that the Kekulé counts increase exponentially with respect to the number of layers in the nanotubes concerned.
