摘要: The single event transient (SET) effect in nanotube tunneling field-effect transistor with bias-induced electron-hole bilayer (EHBNT-TFET) is investigated by 3-D TCAD simulation for the first time. The effects of linear energy transfer (LET), characteristic radius, strike angle, electrode bias and hit location on SET response are evaluated in detail. The simulation results show that the peak value of transient drain current is up to 0.08 mA for heavy ion irradiation with characteristic radius of 50 nm and LET of 10 MeV·cm2/mg, which is much higher than the on-state current of EHBNT-TFET. The SET response of EHBNT-TFET presents an obvious dependence on LET, strike angle, drain bias and hit location. As LET increases from 2 MeV·cm2/mg to 10 MeV·cm2/mg, the peak drain current increases monotonically from 0.015 mA to 0.08 mA. The strike angle has an greater impact on peak drain current especially for the smaller characteristic radius. The peak drain current and collected charge increase by 0.014 mA and 0.06 fC, respectively, as the drain bias increases from 0.1 V to 0.9 V. Whether from the horizontal or the vertical direction, the most sensitive hit location is related to wt. The underlying physical mechanism is explored and discussed.

The simulation results show that the peak value of transient drain current is up to 0.08 mA for heavy ion irradiation with characteristic radius of 50 nm and LET of 10 MeV·cm2/mg, which is much higher than the on-state current of EHBNT-TFET.
