Abstract
A semiconductor light emitting device includes an epitaxial light emitting structure that includes a light emitting component. The light emitting component includes a multiple quantum well structure which contains a plurality of first periodic layered elements, each of which includes first, second and third layers alternately stacked on one another. For each of the first periodic layered elements, the first, second and third layers respectively have first, second and third energy bandgaps (Eg, Eg, Eg) that satisfy a relationship of Eg<Eg<Eg. The third layer has a thickness smaller than that of the first layer. Also disclosed herein is another embodiment of the aforementioned semiconductor light emitting device.
