Abstract :
In this contribution, we report on the analysis of charge transport in graphene nanoribbons by means of timedomain and frequency-domain techniques. The former can be applied in order to describe the Maxwell/Schroedinger coupled system of equations, and the letter are used to solve the Poisson/Schroedinger system in a quasi static framework. A frequency-domain example about the self-consistent solution of laterally coupled graphene nanoribbons is reported. A time-domain example is also reported, showing the effect of the self-generated electromagnetic field, that may affect the dynamics of the charge wavepacket.
