The energy of the undoped system is assumed to be included in the definition of its equilibrium lattice structure and vibrations; then it is a modulation of the energy of additional charges that is of interest to us

This implies a uniform distribution of excess charges over the lattice sites and relatively low temperatures. It is well known that one-dimensional electron-phonon systems can be unstable with respect to the Peierls distortion and exhibit formation of nonuniform polaronic distortions. For not very small carbon nanotubes, however, these effects seem practically irrelevant. The estimated transition temperatures

We expect that thermal excitation of charges into higher lying energy bands will decrease the magnitude of enhanced dimensional changes (compare to the discussed effect of the increased injection level). Such an effect would be more significant for larger tubes. Since the separation between energy bands is large compared with thermal energy at room temperature for not too large nanotubes, we suspect that thermal corrections will be small at room temperature
