Quantum Corrected Drift-Diffusion Simulation


  • Quantum-correction to drift-diffusion simulator for nanoscale bulk MOSFETs.


  • Ballistic mobility added to scattering limited mobility.
  • Ballistic transport: Caughy-Thomas model modified with Monte-Carlo simulation data.
  • Quantum Confinement: EOTelec calibrated with 1D Schroedinger-Poisson solver.


  • Agreement with experimental data (Intel 32 nm/Samsung 20 nm).
  • Performance increase slow-down predicted for future nodes.
