The possibilities of developing ZnSe blue-green lasers with new materi
als and layer structures are studied. In particular, it is considered:
(i) the use of an ''inverted'' laser structure, n-on-p configuration,
having p-type barrier reduction layers of III-V compound semiconducto
rs which are sandwiched between the substrate and the device and (ii)
the use of ZnMnSSe as a cladding layer. Electronic band structures, cu
rrent-voltage curves, and light-current curves are calculated for the
lasers with inverted layer structures. Preliminary results of a study
of ZnMnSSe layers grown by the molecular beam epitaxy method are also
presented.
