    摘要: According to example embodiments, a semiconductor light emitting device includes a first semiconductor layer, a pit enlarging layer on the first semiconductor layer, an active layer on the pit enlarging layer, a hole injection layer, and a second semiconductor layer on the hole injection layer. The first semiconductor layer is doped a first conductive type. An upper surface of the pit enlarging layer and side surfaces of the active layer define pits having sloped surfaces on the dislocations. The pits are reverse pyramidal spaces. The hole injection layer is on a top surface of the active layer and the sloped surfaces of the pits. The second semiconductor layer doped a second conductive type that is different than the first conductive type.

    摘要: A semiconductor device includes a silicon substrate; a nitride nucleation layer disposed on the silicon substrate; at least one superlattice layer disposed on the nitride nucleation layer; and at least one gallium nitride-based semiconductor layer disposed on the superlattice layer. The at least one superlattice layer includes a stack of complex layers, each complex layer including a first layer and a second layer such that each of the complex layers has a plurality of nitride semiconductor layers having different compositions, at least one of the plurality of nitride semiconductor layers having a different thickness based on a location of the at least one nitride semiconductor layer within the stack, and at least one stress control layer having a thickness greater than a critical thickness for pseudomorphic growth.
