AB - <p style="text-align: justify;">Throughout this paper, we study the spectrum of a periodic Schrödinger
operator on a zigzag super carbon nanotube, which is a generalization of the zigzag
carbon nanotube. We prove that its absolutely continuous spectrum has the band structure.
Moreover, we show that its eigenvalues with infinite multiplicities consisting of
the Dirichlet eigenvalues and points embedded in the spectral band for some corresponding
Hill operator. We also give the asymptotics for the spectral band edges.</p>
