Abstract
A multi-quantum well structure includes at least one lamination layer, each lamination layer includes a first film layer, an insertion layer and a second film layer, and the at least one lamination layer includes a plurality of lamination layers which are stacked with each other. The insertion layer is located between the first film layer and the second film layer. The insertion layer includes at least one of a monomer structure and a superlattice structure, the first film layer is doped with elements of In, Ga and N, the insertion layer is doped with elements of Al, Ga and N, and the second film layer is doped with elements of Ga and N. The multi-quantum well structure has ability to emit a light with a longer wavelength, and defects and other undesirable phenomena, caused by growing the first film layer with low-temperature epitaxy, may be prevented.
