MOVPE growth of zincblende magnesium sulphide

The successful growth of MgS epitaxial layers with the MOVPE technique is reported. The samples were grown on GaAs substrates in a classical horizontal reactor, using bis(methylcyclopentadienyl) magnesium and H 2 S as precursors. The zincblende structure of MgS layers is evidenced by careful X-ray diffraction analysis. The lattice constant is found to be about 5.66 A. The influence of the growth temperature on the morphology and quality of the layers is studied in detail.
