Latest Patents

Jung Han's latest patents include innovations in Group II-VI compound semiconductor light-emitting devices. One of his patents discloses an ohmic contact for these devices, which includes at least one II-VI quantum well region of a well layer disposed between first and second barrier layers. The quantum well region is sandwiched between first and second cladding layers of a II-VI semiconductor material. The first cladding layer is formed on and lattice matched to the first barrier layer and to a substrate of a III-V compound semiconductor material. The second cladding layer is lattice matched to the second barrier layer. The quantum well layer comprises a II-VI compound semiconductor material having the formula A.sub.x B.sub.(1-x) C, wherein A and B are two different elements from Group II and C is at least one element from Group VI. When the second cladding layer has a p-type conductivity, a graded bandgap ohmic contact can be utilized. This contact can be a single continuously graded II-VI p-type region or a plurality of cells, each having first and second thin layers of first and second p-type II-VI semiconductor materials respectively. Another embodiment of his invention discloses a monolithic multicolor light-emitting element capable of emitting four colors, along with a method for fabricating the same. This multicolor element includes four II-VI semiconductor light-emitting devices formed on a single III-V substrate.
