Gate Control and Sub-Threshold Swing in BTBT Comparison of in pin InAs Devices

Gate Control and Sub-Threshold Swing in BTBT Comparison of in pin InAs Devices Mathieu Luisier, Gerhard Klimeck

Objective:

  • Low voltage, good turn-on/off switches
  • Develop low sub-threshold swing FETs with band-to-band-tunneling (BTBT)
  • Provide guidance to experiments

Approach:

  • Utilized OMEN - atomistic, full band quantum transport simulator
  • 3 diff. geom., InAs, 20nm gates. 6nm body/diameter, 1nm Oxide, 5e19/cm3

Result:

  • Dramatically different sub-thresholds
  • Slightly different gate controls

Impact:

  • BTBTdevices much more sensitive to smooth band bending than expected
  • gate all-around NW fairs best.
