Performance of Trigated Silicon Nanowire pMOSFETs :
Surface and Orientation dependence

Performance of Trigated Silicon Nanowire pMOSFETs :
Surface and Orientation dependence		 Saumitra Raj Mehrotra & Gerhard Klimeck

Objective:

  • Study performance of SiNW pMOSFETs.
  • Study of impact of surface and transport orientation

Approach:

  • Used Bandstructure Lab (powered by OMEN)

Impact:

  • Channel orientation is more important in nanowire FETs compared to surfaces.
  • Need to move to other channel materials like Ge to further improve ION in PMOSFETs.
  • Results presented in IEEE WMED, 2009
