    Abstract: A semiconductor structure includes a III-nitride substrate and a first III-nitride epitaxial layer of a first conductivity type coupled to the III-nitride substrate. The semiconductor structure also includes a first III-nitride epitaxial structure of the first conductivity type coupled to the first III-nitride epitaxial layer and a second III-nitride epitaxial structure of the first conductivity type coupled to the first III-nitride epitaxial structure. The semiconductor structure further includes a second III-nitride epitaxial layer coupled to the first III-nitride epitaxial structure. The second III-nitride epitaxial layer is of a second conductivity type and is not electrically connected to the second III-nitride epitaxial structure.

    Abstract: A vertical JFET includes a III-nitride substrate and a III-nitride epitaxial layer of a first conductivity type coupled to the III-nitride substrate. The first III-nitride epitaxial layer has a first dopant concentration. The vertical JFET also includes a III-nitride epitaxial structure coupled to the first III-nitride epitaxial layer. The III-nitride epitaxial structure includes a set of channels of the first conductivity type and having a second dopant concentration, a set of sources of the first conductivity type, having a third dopant concentration greater than the first dopant concentration, and each characterized by a contact surface, and a set of regrown gates interspersed between the set of channels. An upper surface of the set of regrown gates is substantially coplanar with the contact surfaces of the set of sources.
