    摘要: A semiconductor structure includes a substrate, a first III-V compound layer over the substrate, one or more sets of III-V compound layers over the first III-V compound layer, a second III-V compound layer over the one or more sets of III-V compound layers, and an active layer over the second III-V compound layer. The first III-V compound layer has a first type doping. Each of the one or more sets of III-V compound layers includes a lower III-V compound layer and an upper III-V compound layer over the lower III-V compound layer. The upper III-V compound layer having the first type doping, and the lower III-V compound layer is at least one of undoped, unintentionally doped having a second type doping, or doped having the second type doping. The second III-V compound layer is either undoped or unintentionally doped having the second type doping.
