Abstract: Devices comprising, and a method for fabricating, a remote doped high performance transistor having improved subthreshold characteristics are disclosed. In one embodiment a field-effect transistor includes a channel layer configured to convey between from a source portion and a drain portion of the transistor when the transistor is in an active state. Further, the field-effect transistor includes a barrier layer adjacent to the channel layer. The barrier layer comprises a delta doped layer configured to provide carriers to the channel layer of the transistor, while preferably substantially retaining dopants in said delta-doped layer.
