Gallium Nitride Power Transistor

Abstract

The disclosure relates to a Gallium Nitride power transistor, comprising: a buffer layer; and a barrier layer having a top side, a bottom side, the bottom side facing the buffer layer, the bottom side of the barrier layer is placed on the buffer layer; an interlayer interposed between a p-type doped Gallium Nitride layer and a metal gate layer, the interlayer is made of a III-V compound semiconductor comprising a combination of at least one group III element with at least one group V element, the p-type doped Gallium Nitride layer is placed on the top side of the barrier layer, the metal gate layer is electrically connected to the p-type doped Gallium Nitride layer via the interlayer to form a rectifying metal-semiconductor junction with the p-type doped Gallium Nitride layer.
