Patent ID: 7902556

Claim:
A semiconductor light-emitting device, comprising: a Si substrate; a silver (Ag) transition layer which is formed on a surface of the Si substrate, wherein the Ag transition layer covers the Si substrate surface, wherein the Ag transition-layer thickness is between 2 and 50 angstroms, and wherein the Ag transition layer exhibits similar lattice structure as the Si substrate; and an InGaAlN, ZnMgCdO, or ZnBeCdO-based semiconductor light-emitting structure which is epitaxially grown on the Ag-coated Si substrate, wherein the InGaAlN, ZnMgCdO, or ZnBeCdO-based semiconductor light-emitting structure is in contact with the Ag transition layer, whereby the Ag transition layer prevents the Si substrate surface from forming an amorphous overcoat with reactant gases used for growing the semiconductor light-emitting structure.
