Linearity characteristics of hetero-gatedielectric tunneling field-effect transistors (HG TFETs) have been compared with those of high-k-only and SiO₂-only TFETs in terms of IIP3 and P1dB. It has been observed that the optimized HG TFETs have higher IIP3 and P1dB than high-k-only and SiO₂-only TFETs. It is because HG TFETs show higher transconductance (gm) and current drivability than SiO₂-only TFETs and gm less sensitive to gate voltage than high-k-only TFETs.
