Abstract

Abstract A field effect transistor having an excellent transfer conductance and an improved gate leakage current and breakdown voltage is provided. In the transistor, a multiquantum barrier gate structure 4 is arranged along a channel layer 3 and having an effect of reflecting incident carriers as waves in with phase conditions capable of allowing mutual enhancement of the incident and reflected waves in a region between a channel layer 3 and a gate electrode 10 and/or in a region opposite to the gate electrode 10 relative to the channel layer 3. <IMAGE>
