SEMICONDUCTOR SUBSTRATE, LIGHT EMITTING DEVICE, AND ELECTRONIC DEVICE

摘要

A semiconductor substrate includes a first conductivity type semiconductor layer on a substrate, and a control layer arranged between the substrate and the first conductivity type semiconductor layer. The control layer includes a first nitride semiconductor layer including Al, multiple nanostructures arranged on the first nitride semiconductor layer, and a second nitride semiconductor layer which is arranged on the first nitride semiconductor layer and includes Ga.
