Nanotubes are generally not perfectly straight cylinders and the local curvature can influence transport properties. As shown by da Costa , charged particles moving on a curved surface experience an effective potential which modifies their dynamics. In this paper, we solve a one-electron SchrÃ¶dinger equation in a distorted nanotube with open boundary conditions. We find that the deformations may open bandgaps suggesting their use in the design of nanotubebased electronic devices.
