Ab initio exploration of electron-optical phonon interaction in nanotubes
Abstract
Transport properties of carbon nanotubes (CNTs) has attracted considerable attention ever since their discovery in 1991. The low bias voltage characteristic has been widely studied. Recently there has been experimental interest in the conductance of CNTs under high bias. Experiments show that under these conditions, the electron-phonon interaction introduces a mean-free path that is an order of magnitude shorter than at low bias. This talk presents what is to our knowledge the first ab initio exploration of the possibility that the short mean free path at high bias results from coupling between conduction electrons and optical phonons.
