Electron Electron and Electron Phonon Interactions

At high temperature where the Coulomb blockade is unimportant, tunneling into a metallic nanotube is consistent with predictions for tunneling into a Luttinger liquid which is formed due to strong electron interactions. This is described in 1.3.1. Section 1.3.2 treats the effects of electron-phonon interactions at high electric fields. Large-bias current-voltage characteristics using low-resistance contacts suggest that the main scattering mechanism for high-energy electrons is due to optical or zone-boundary phonons.
