Metastable II-VI sulphides: Growth, characterization and stability

TEM shows that occasionally both ZB and RS phases may be present simultaneously. The small RS inclusions seem to stabilise the ZB phase against relaxation and do not propagate through the crystal. Examination of the totally converted films suggests that they are composed of different rocksalt domains and may not have transformed via the mechanism which has been suggested as the lowest route for bulk MgS.
