Numerical Techniques for the Analysis of Charge Transport and Electrodynamics in Graphene Nanoribbons
In this paper, we report on multiphysics fullwave techniques in the frequency (energy)‐domain and the time‐domain, aimed at the investigation of the combined electromagnetic‐coherent transport problem in carbon based on nano‐structured materials and devices, e.g., graphene nanoribbons. The frequency...

| description | In this paper, we report on multiphysics fullwave
techniques in the frequency (energy)‐domain and
the time‐domain, aimed at the investigation of the
combined electromagnetic‐coherent transport problem in
carbon based on nano‐structured materials and devices,
e.g., graphene nanoribbons.
The frequency‐domain approach is introduced in order to
describe a Poisson/Schrödinger system in a quasi static
framework. An example of the self‐consistent solution of
laterally coupled graphene nanoribbons is shown.
The time‐domain approach deals with the solution of the
combined Maxwell/Schrödinger system of equations. The
propagation of a charge wavepacket is reported, showing
the effect of the self‐generated electromagnetic field that
affects the dynamics of the charge wavepacket. |
