Abstract:
    A light emitting device includes an active layer including atoms A of a matrix semiconductor having a tetrahedral structure, a heteroatom D substituted for the atom A in a lattice site, and a heteroatom Z inserted into an interstitial site positioned closest to the heteroatom D, the heteroatom D having a valence electron number differing by 1 or -1 from that of the atom A, and the heteroatom Z having an electron configuration of a closed shell structure through charge compensation with the heteroatom D, and an n-electrode and a p-electrode adapted to supply a current to the active layer.
