Abstract :
A model has been developed which can more accurately represent dynamic transport in combinations of one dimensional ballistic electron waveguides such as carbon nanotubes. The model parameters are just the Fermi velocity and conductance of the electron gas , thus avoiding the confusing quantum capacitance and conductance terms. Logical extensions of this model should permit design and simulation of high frequency amplifiers in these exciting new materials.
