CDTE/MNTE SHORT-PERIOD SUPERLATTICES - ELASTIC PROPERTIES

We report on the structural characterization of CdTe/MnTe short-period superlattices. The critical thickness of MnTe on CdTe layers was determined by reflection high-energy electron diffraction experiments. Detailed high-resolution x-ray diffraction measurements and the computer simulation of the measured spectra enabled the determination of the zinc blende MnTe elastic properties in the superlattices. T.he knowledge of these properties allowed the growth of strain balanced CdTe/MnTe superlattices pseudomorphic to a Cd0.96Zn0-04Te buffer. The superlattices exhibited x-ray linewidths of about 100 arcsec.
