Abstract
The integral electron density of states at the Fermi level in carbon multilayer nanotubes, which belong to quasi-one-dimensional systems, has been calculated within the tight-binding approximation. It is shown that the density-of-state functions for nanotubes with 20 or more layers and for quasi-two-dimensional graphites virtually coincide. This agreement explains the successful application of the band theory of quasi-two-dimensional graphite to the description of magnetic properties of nanotubes over a wide temperature range.
