Abstract

Extremely scaled high-k gate dielectrics with high quality electrical interfaces with arsenide (As) and antimonide (Sb) channels are used to demonstrate complimentary 'all III-V' Heterojunction Vertical Tunnel FET (HVTFET) with record performance at -VDS=0.5V. The p-type TFET (PTFET) has ION =30μA/μm and ION/IOFF =105, whereas the n-type TFET (NTFET) has ION =275μA/μm and ION/IOFF=3×105, respectively. NTFET shows 55mV/decade switching slope (SS) while PTFET shows 115mV/decade SS in pulsed mode measurement. Vertical TFET offers 77% higher effective drive strength than Si-FinFET for given inverter standard cell area. Energy-delay performance of TFET shows gain over CMOS for low VDD logic applications.
