Abstract
An optical semiconductor device is provided with a p-type ZnSe semiconductor layer. Si, Cl and O atoms are added, as dopants, to the ZnSe semiconductor layer. Associations of the Si, Cl and O atoms are formed to define a shallow acceptor level in the semiconductor layer. Each of the associations comprises one Si atom, one Cl atom and one O atom by which the lattice points of Se are displaced between those crystal lattice points in the semiconductor layer which are adjacent to one another.
