TlGaTe2 crystals were grown and purified by successive recrystallizati
ons. A stoichiometric analysis gave maximum deviations of the nominal
TlGaTe2- composition of similar to 5%. An X-ray diffraction study gave
the following results for the structure of the obtained crystals: Spa
ce group Is D-4h(18), lattice parameters a=8.455A and c=6.871A. A morp
hological investigation of the obtained crystals reveals the fiberlike
structure of this material.
