Abstract
A semiconductor structure includes a substrate. The semiconductor structure further includes a buffer layer over the substrate, wherein the buffer layer comprises a plurality of III-V layers, and a dopant type of each III-V layer of the plurality of III-V layers is opposite to a dopant of adjacent III-V layers of the plurality of III-V layers. The semiconductor structure further includes an active layer over the buffer layer. The semiconductor structure further includes a dielectric layer over the active layer.
