D2d symmetry of CuInS2:Co2+ single crystals
TL;DR: In this paper, the absorption spectra of CuInS2:Co2+ single crystals were synthesized by chemical transport reaction using iodine as a transporting medium and two broad peaks due to 4 A 2 (4 F )→ 4 T 1 ( 4 F ) transitions of Co2+ ions in the Td symmetry were observed.

A temperature variation method for the growth of chalcopyrite crystals by iodine vapour transport
TL;DR: In this paper, a two-four fold increase in the size of some I-III-VI compounds was obtained by means of a time-varying temperature profile procedure, which consists in a gradual raising of the source temperature, which allows, first, a reduced primary nucleation, and, secondly, the avoidance of constitutional undercooling during the first stages of the nucleus growth.
