Query: Electronic properties of disclinated nanostructured cylinder   The electronic structure of nanocylinder without and with a small
perturbation is investigated with the help of calculation of the local density
of states. A continuum gauge field-theory model is used for this purpose. In
this model, Dirac equation is solved on a curved surface. The local density of
states is calculated from its solution. The case of 2 heptagonal defects is
considered. This paper is an extension of our previous work [1] where one
heptagonal and one pentagonal defects in hexagonal graphene network were
compared. The metallization for the perturbed cylinder structure is found.
