摘要
We report Monte Carlo (MC) simulation results showing applied bias dependent spatial velocity oscillations for semiconducting single-walled zig-zag carbon nanotubes (CNTs). MC simulations show velocity oscillations in CNTs at different lengths due to high scattering rates associated with optical phonon emissions in the one-dimensional CNT system. The frequencies of these oscillations are as high as 30 THz. In addition, we investigate average ensemble electron velocities as a function of tube length.
