Presentation Transcript


Objective

Electron-Phonon Scattering in NW FETsMathieu Luisier and Gerhard Klimeck PRB 80, 155430 (2009)

Objective:

  • Solve one of the Grand Challenge problems in device simulation: the simultaneous inclusion of an atomistic description of the simulation domain, a full-band description of the materials, and electron-phonon scattering

Approach:

  • Use of the sp3d5s* tight-binding model to describe electrons and holes

  • Use of the Non-equilibrium Green’s Function (NEGF) formalism to solve quantum transport

  • Electron-phonon scattering in the self-consistent Born approximation

  • Efficient multi-level parallelizationscheme

Results and Impacts:

  • Modification of current distribution and band edges and reduction of drain current

  • First dissipative quantum transport simulations of realistically extended nanowire transistor structures

Ongoing Work:

  • Mobility extraction in n- and p-doped nanowires with different crystal orientations

  • Look for experimental data to verify the model
