摘要：

Using the π-band tight-binding (TB) model and the quantum box boundary condition, we have discussed how both of the applied strain and finite-length affect the energy bands of metallic carbon nanotubes (CNTs). It is found that, for finite-length CNTs, energy gap for the armchair tube under uniaxial strain and metallic zigzag tube under torsional strain will oscillate with increasing strain, which do not exist in the case of infinite-length CNTs, and will be able to be observed by experiments in future.
