Title:
ELECTRIC FIELD EFFECT TRANSISTOR
Document Type and Number:
WIPO Patent Application WO/2023/228267
Kind Code:
A1
Abstract:
This electric field effect transistor (10) comprises, on a surface in the following order, a source electrode (111), a first gate electrode (112), and a drain electrode (113), and comprises, in a direction perpendicular to the surface, in the following order: a first barrier layer (104); a second gate electrode (103) disposed inside the first barrier layer; a first channel layer (105) composed of a semiconductor; a second barrier layer (106) composed of a semiconductor having a larger energy gap than the first channel layer, and including a δ-doped layer; a second channel layer (107) composed of a semiconductor having a smaller energy gap than the second barrier layer; a third barrier layer (108); and the first gate electrode. Consequently, the present invention is able to provide a field effect transistor that is capable of high output and high frequency operation.
