Jr. Buschert et al., UNUSUAL ELASTIC-CONSTANTS OF CUBIC MNTE IN STRAINED-LAYER SUPERLATTICES MEASURED BY X-RAY-DIFFRACTION, Physical review. B, Condensed matter, 49(7), 1994, pp. 4619-4622
Elastic constants of the recently grown nonequilibrium zinc-blende for
m of MnTe were measured. Strained layer MnTe/ZnTe superlattices in whi
ch MnTe appears in this zinc-blende form were studied using triple cry
stal x-ray diffraction. The diffraction spectra were fitted using a dy
namical model to determine the thickness and the lattice constants of
each layer. From these and other measurements, the elastic constants C
-11 and C-12 of MnTe were determined to be 2.22+/-0.1 and 1.16+/-0.1,
respectively. These values are very low compared to all other zinc-ble
nde or diamond structure materials investigated so far.
