FIELD: solid-state physic.
SUBSTANCE: silver thiogallate (AgGaS2) single crystal are obtained by interaction of starting elements with indium addition in amount of 0.04-5 wt.% at elevated temperature in horizontally oriented ampoule and subsequent vertical directional crystallization in sealed ampoule. Claimed material has absorption coefficient of λ = 0.1 cm-1.
EFFECT: optically homogeneous materials without cracks and polysynthetic twinned crystals.
