摘要

In order to understand the response of conductive materials to high-frequency electrical or optical excitations, the interplay between carrier transport and electrodynamics must be captured. We present our recent work on developing EMC/FDTD/MD, a self-consistent coupled simulation of semiclassical carrier transport, described by ensemble Monte Carlo (EMC), with full-wave electrodynamics, described by the finite-difference time-domain (FDTD) technique and molecular dynamics (MD) for sub-grid-cell interactions. Examples of room-temperature terahertz-frequency transport simulation of doped silicon and back-gated graphene are shown.
