Gallium nitride (GaN) based transistor with multiple p-GaN blocks

Gallium nitride (GaN) based transistor with multiple p-GaN blocks

In some examples, a gallium nitride (GaN)-based transistor, comprises a substrate; a GaN layer supported by the substrate; an aluminum nitride gallium (AlGaN) layer supported by the GaN layer; a p-doped GaN structure supported by the AlGaN layer; and multiple p-doped GaN blocks supported by the AlGa...

Zusammenfassung:In some examples, a gallium nitride (GaN)-based transistor, comprises a substrate; a GaN layer supported by the substrate; an aluminum nitride gallium (AlGaN) layer supported by the GaN layer; a p-doped GaN structure supported by the AlGaN layer; and multiple p-doped GaN blocks supported by the AlGaN layer, each of the multiple p-doped GaN blocks physically separated from the remaining multiple p-doped GaN blocks, wherein first and second contours of a two-dimensional electron gas (2DEG) of the GaN-based transistor are at an interface of the AlGaN and GaN layers.
