Recycled Crystallisation of ZnTe by Evaporation-Condensation

ZnTe crystals have been grown by self-selecting vapour growth SSVG in a vertical, modified system, which reduces contact of the crystallised material with foreign materials to the minimum possible. Geometrical stability of the growth system is increased. The obtained crystals are of the sizes slightly below 10 mm and the “rocking curve” measurement results in the value of 36 arc sec. Distinct purification effect appears. The lattice constant of ZnTe is equal to 0.61036 nm.
