Abstract

A TFET includes a source region (110, 210), a drain region (120, 220), a channel region (130, 230) between the source region and the drain region, and a gate region (140, 240) adjacent to the channel region. The source region contains a first compound semiconductor including a first Group III material and a first Group V material, and the channel region contains a second compound semiconductor including a second Group III material and a second Group V material. The drain region may contain a third compound semiconductor including a third Group III material and a third Group V material.
