| Popis: | The MgTe powder was prepared by reaction of stoichiometric quantities of Mg and Te in a pure graphite crucible in vacuum at 480 °C during 48 hr. MgTe single crystals were grown by vacuum sublimation in a two-zone furnace at a sublimation temperature of 960 °C. The crystals are transparent hexagonal columns with a length up to 12 mm and extremely hygroscopic. They have a high index of refraction. The natural faces are parallel to (10 1 0) (prism planes) and (0001) (basal plane). |
