Growth, morphology and electrical properties of (thallium selenide)x-(indium selenide)1 − x mixed crystals (x = 0.0, 0.1, 0.2,…, 0.9, 1.0)

Crystals of different members of the family TlxIn1 − xSe (x = 0.0, 0.1, 0.2,…, 0.9, 1.0) were grown by direct synthesis of their constituent elements. The crystals are forming bundles of parallel rectangular fibers. Their stoichiometry was examined by means of X-ray microanalysis. Preliminary electrical measurements along the fibers show a strong dependence of the conductivity on x.
