We present a GaSb/In As junctionless tunnel FET and investigate its static device characteristics. The proposed structure presents tremendous performance at a very low supply voltage of 0.4 V. The key idea is to the present device architecture, which can be exploited as a digital switching device for sub 20 nm technology.Numerical simulations resulted in an IOFF of 8×10-17A/ m, ION of 9 A/ m, ION/IOFF of 1×1011,subthreshold slope of 9.33 m V/dec and DIBL of 87 m V/V for GaSb/InAs JLTFET at a temperature of 300 K,gate length of 20 nm, HfO2 gate dielectric thickness of 2 nm, film thickness of 10 nm, low-k spacer thickness of 10 nm and VDD of 0.4 V.
