Beyond-CMOS Tunnel FET Simulator

Interactive Tunnel FET (TFET) vs classical MOSFET simulator: watch band-to-band quantum tunneling switch current through a p-i-n junction with a sub-60mV/decade subthreshold swing, and compare live I-V curves against a thermionic-limited MOSFET.

This simulator compares two transistor switching mechanisms side by side: the thermionic emission that governs every classical MOSFET, and the band-to-band quantum tunneling used by Tunnel FETs (TFETs) — a leading beyond-CMOS device concept. Sweep the gate voltage to watch electrons cross the channel by climbing over a potential barrier (MOSFET) or tunneling directly through the forbidden gap of a p-i-n junction (TFET), while the live I-V chart plots how much steeper the TFET's subthreshold turn-on can be compared to the classical thermal limit.

⚙ Under the hood

Compare a classical MOSFET's thermionic switching against a Tunnel FET's band-to-band quantum tunneling through a p-i-n junction. Sweep the gate voltage to watch electrons hop over the barrier or tunnel straight through it, while a live log-scale I-V chart shows the TFET dropping below the 60 mV/decade thermal limit.
