Electrostatically induced interconnect structures in graphene are an alluring alternative for nanoribbons to be used in future integrated circuits (ICs) because of the avoidance of edge scattering. In this contribution, these structures are analyzed using a novel first-principles modeling approach, based on higher-order conservative partitioned Runge-Kutta time stepping for the (2+1)D Dirac equation. The validity and applicability of the modeling tool are demonstrated by applying it to a bent interconnect and to a coupler.
An FDTD-TDDFT method for the EM/QM co-simulation of nanowire systems in the Lorenz gauge
Real-time time-dependent density functional theory (TDDFT) constitutes a cornerstone in the modeling of nanoscale materials. Although numerous application areas have already benefited from the technique,
