摘要：

The energy gap of semiconducting graphitic tubules with radius R and chiral angle theta is studied from an analytical approach based on the tight-binding approximation, to find out its dependence on their chirality. It is found that the energy gap has a part proportional to cos(3theta)/R2, in agreement with our recent prediction deduced from a numerical investigation.
