    摘要： The light emitting device comprises a substrate 10 of a p-type semiconductor; an active layer 20 formed of a plurality of quantum dot layers 18 stacked, the quantum dot layers 18 having three-dimensional grown islands self-formed by S-K mode, respectively; and an n-type semiconductor layer 22 formed over the active layer. Because of the p-type semiconductor, over which the active layer 20 is formed on, and the n-type semiconductor, which is formed over the active layer 20, lower layer regions of the active layer 20, where good quantum dots 19 are formed are nearer to regions of the active layer 20, which are nearer to the p-type semiconductor. Accordingly, the radiation recombination between the holes and electrons takes place mainly in the regions where those of the quantum dots, which are of good quality. Thus, even when a number of the quantum dot layers 18 are stacked, good device characteristics can be obtained.

    摘要： A group II-VI epitaxial layer grown on a (111) silicon substrate has a lattice mismatch which is minimized, as between the group II-VI epitaxial layer and the silicon substrate. The grown group II-VI epitaxial layer also has a (111) plane at the interface with the substrate, and a 30.degree. in-plane rotation slip is formed at the interface between the (111) silicon substrate and the group II-VI epitaxial layer. The above structure is produced by a metal organic chemical vapor deposition method (MOCVD), in which a mol ratio of a group VI gas source supply to a group II gas source supply is kept greater than 15 during the growth. The (111) silicon substrate is preferably mis-oriented toward the direction of the silicon substrate. When a HgCdTe layer is grown on the epitaxial layer, the product thus formed has utility as a monolithic infrared detector in which a plurality of detector elements are formed in the HgCdTe layer and a signal processing circuit is formed in the silicon substrate.
