Claim:
1. An intra-band tunnel field effect transistor (TFET) device, comprising: a source region separated from a drain region by a channel region, wherein the source region, the drain region, and the channel region comprise materials with energy bands having bandgaps with values that form a conduction band between the source region and the drain region and a valence band between the source region and the drain region, wherein the conduction band has only one conduction band energy barrier between the source region and the drain region that is different than an only valence band energy barrier within the valence band between the source region and the drain region; and a gate region configured to generate an electric field that varies the conduction band energy barrier and the valence band energy barrier to selectively allow quantum mechanical tunneling of electrons within the conduction band or to selectively allow quantum mechanical tunneling of holes within the valence band.
