Claim Text:
1. A tunnel field-effect transistor (TFET) device, comprising: first and second semiconductor contact regions separated by a semiconductor channel region; a channel gate overlying the channel region; and first and second doping gates overlying the first and second contact regions respectively; and further comprising first and second contact electrodes connected to the first and second contact regions respectively, wherein at least one of the first and second doping gates is shorted to the corresponding contact electrode, and wherein application of a positive voltage level at the first doping gate and a negative voltage level at the second doping gate produces an n-type first contact region and a p-type second contact region, and reversing the voltage levels at the doping gates produces a p-type first contact region and an n-type second contact region.
