EMC/FDTD/MD simulation of carrier transport and electrodynamics in two-dimensional electron systems

摘要

We present the implementation and application of a multiphysics simulationtechnique to carrier dynamics under electromagnetic excitation in supportedtwo-dimensional electronic systems. The technique combines ensemble Monte Carlo(EMC) for carrier transport with finite-difference time-domain (FDTD) forelectrodynamics and molecular dynamics (MD) for short-range Coulombinteractions among particles. We demonstrate the use of this EMC/FDTD/MDtechnique by calculating the room-temperature dc and ac conductivity ofgraphene supported on SiO2.
