Abstract

A field effect transistor comprises a source electrode, a drain electrode, a channel layer between the source electrode and the drain electrode, a gate electrode for controlling electric current in the channel layer, and a superlattice layer interposed between the channel layer and the gate electrode, the superlattice layer having a plurality of constituent thin layers perpendicular to a direction of electric current in the channel layer.
