Claim:
1. A metal-oxide-semiconductor field-effect phototransistor comprising: a substrate; a single-crystalline semiconductor film comprising: a radiation-receiving surface; an opposing, substrate-facing surface; a source region; a drain region; and a channel region; a gate stack comprising a gate dielectric and a gate electrode, wherein the gate stack is disposed on the substrate-facing surface of the single-crystalline semiconductor film, between the channel region of the single-crystalline semiconductor film and the substrate; a source electrode disposed on the substrate-facing surface of the single-crystalline semiconductor film, between the source region of the single-crystalline semiconductor film and the substrate; a drain electrode disposed on the substrate-facing surface of the single-crystalline semiconductor film, between the drain region of the single-crystalline semiconductor film and the substrate; and an antireflective coating on the radiation-receiving surface of the single-crystalline semiconductor film.
