Abstract
A gallium nitride (GaN)-based junction field-effect transistor (JFET) can include a GaN drain region having a top surface extending in a lateral dimension, a source region, and a GaN channel region of a first conductivity type coupled between the source region and the GaN drain region and operable to conduct electrical current between the source region and the GaN drain region. The JFET can also include a blocking layer disposed between the source region and the GaN drain region such that the GaN channel region is operable to conduct the electrical current substantially along the lateral dimension in a laterally-conductive region of the GaN channel region, and a GaN gate region of a second conductivity type coupled to the GaN channel region such that the laterally-conductive region of the GaN channel region is disposed between at least a portion of the blocking layer and the GaN gate region.
