Abstract
Abstract We have studied the hybridization and curvature effects of zigzag nanotubes in the framework of π ‐tight‐binding ( π TB) approximation. Three parameters were used for the first neighbor interactions. By adjusting the hoping parameters to the results calculated in all‐valence tight‐binding (AVTB) method we could obtain metallic electronic structure for the (5,0) nanotube.
