  • This paper introduces about the difference between the tunneling currents in the 1D and 2D directions for the calculation of the band-to-band tunneling currents of the tunneling field effect transistors. In the two-dimensional tunneling, diagonal tunneling is not calculated in the one-dimensional tunneling so that more accurate tunneling current can be calculated. Simulation results show that the tunneling in the two - dimensional direction has no effect on the voltage above the threshold voltage, but it affects the subthreshold swing below the threshold voltage.

  • The structure guide lines of pocket tunnel field effect transistor(TFET) considering Line and Point tunneling are introduced. As the pocket doping concentration or thickness increase, on-current $I_{on}$ increases. As the pocket thickness or gate insulator increase, subthreshold swing(SS) increases. Optimal structure reducing the hump effects should be proposed in order to enhance SS.
