Claim:
1. A field effect transistor comprising: a layer of single-crystalline inorganic semiconductor comprising a first sublayer in which the semiconductor is n-type doped or p-type doped and a second, oppositely doped sublayer adjacent to the first sublayer; a trench bisecting the first sublayer and extending into the second sublayer to provide a source region in the first sublayer on one side of the trench, a drain region in the first sublayer on the opposite side of the trench, and a channel region in the second sublayer above the trench, wherein the channel region has a length corresponding to the width of the trench; a gate dielectric disposed on the channel region; a gate contact disposed on the gate dielectric; a source contact in electrical communication with the source region; and a drain contact in electrical communication with the drain region.
