ABSTRACT:
A light emitting semiconductor device includes a silicon substrate and a compound semiconductor layer disposed on a main plane of the silicon substrate and represented by a general expression InxGayAlzN, wherein x+y+z=1, 0≦x≦1, 0≦y≦1, and 0≦z≦1. The silicon substrate has a groove having an oblique plane corresponding to a plane inclined relative to the substrate's main plane by 62 degrees or a plane inclined relative to the inclined plane in any direction within three degrees, and on the oblique plane a plurality or quantum well layers different in thickness are stacked.
