Abstract
Full-wave multiphysics techniques aimed at the investigation of the combined electromagnetic-coherent transport phenomena in carbon-based nano-structures/devices are presented. Advanced numerical tools, in the frequency (energy)-domain and time-domain and in multi-scale environment are derived. The quantum transport is modeled by i) discrete Hamiltonians at atomistic scale, ii) Schrödinger equation, and/or Dirac/Dirac-like eqs. at continuous level. In the frequency-domain, a rigorous Poisson-coherent transport equation system is provided. In the time-domain, Maxwell equations are self-consistently coupled to the Schrödinger/Dirac equationsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
