Full-band atomistic study of electron-phonon interaction in carbon nanotubes

Abstract

This paper presents a comprehensive study of electron-phonon interactions in carbon nanotubes (CNTs), using the non-equilibrium Green’s function (NEGF) method. The transmission function is calculated to analyze the influence of electron-optical-phonon interactions, which are crucial in determining carrier scattering. Our study includes full-band analysis and atomistic details using the tight-binding approximation. Scattering rates and transmission functions are presented, showing significant impacts at the band center and minimal effects at band edges.
