EPITAXIAL-GROWTH OF ZINCBLENDE ZNSE MGS SUPERLATTICES ON (001)GAAS/

We report the growth of zinc-blende ZnSe/MgS superlattices (SLs) on Ga As (001) substrates. The SLs were grown with metalorganic vapor phase epitaxy by selecting appropriate precursors for Mg and S. MgS naturall y forms rocksalt structures, but zinc-blende MgS layers were grown, Th e lattice constant of MgS was estimated to be 5.59 Angstrom, X-ray dif fraction measurements show that the ZnSe/MgS SLs are grown coherently to the GaAs substrates up to the total thicknesses of similar to 3000 Angstrom.
