Latest Patents

Jinghua Chen holds a patent for a light-emitting device. This device includes a semiconductor epitaxial structure that features a first surface and a second surface. The structure comprises a first semiconductor layer, an active layer, and a second semiconductor layer. The active layer contains a quantum well structure with multiple periodic units, each consisting of a well layer and a barrier layer that has a greater bandgap than the well layer. Notably, the bandgap of the barrier layer of at least one periodic unit near the first surface is smaller than that near the second surface. Additionally, the thickness of the well layer of at least one periodic unit close to the first surface is greater than that near the second surface. In some embodiments, the bandgap of a second spacing layer situated between the active and second semiconductor layers increases from the first surface to the second surface.
