    摘要： A semiconductor laser device for radiating a laser beam from a double heterostructure section in which injected carriers having an energy source of the laser beam are confined consists of a compound semiconductor substrate with a prescribed lattice constant for loading the double heterostructure section, a lattice mismatched active layer with a first lattice constant which is 0.5% to 2.0% larger than the lattice constant of the substrate in the double heterostructure section for radiating the laser beam, a lattice mismatched cladding layer with a second lattice constant which is 0.2% to 2.0% smaller than the lattice constant of the substrate for confining the injected carriers in the active layer, and a cladding layer for confining the injected carriers in the active layer by co-operating with the lattice mismatched cladding layer.

    摘要： This invention provides a semiconductor light-emitting device including a semiconductor substrate consisting of a compound semiconductor of elements in the third and fifth groups of the period table, a first compound semiconductor layer formed directly on at least a portion of the semiconductor substrate and consisting of a compound semiconductor containing at least In and P, and a second compound semiconductor formed directly on the first compound semiconductor layer and consisting of a compound semiconductor of elements in the second and sixth groups of the periodic table. With this arrangement, it is possible to sufficiently prevent the occurrence of defects in the interface between the semiconductor substrate and the second compound semiconductor layer consisting of the compound semiconductor of the elements in the second and sixth groups of the periodic table.
