Abstract

A field-effect semiconductor device includes a channel layer; a barrier structure formed on the channel layer and including a plurality of semiconductor layers; a plurality of ohmic electrodes formed above the barrier structure; and a Schottky electrode formed on the barrier structure between the ohmic electrodes. The barrier structure has an electron-affinity less than that of the channel layer and includes at least two heavily doped layers and a lightly doped layer provided therebetween.
