Thermodynamic feasibility of transition metal dichalcogenide (TMDC) single crystals of Cu Al S₂, Cu Al Se₂, Cu Al Te₂, Cu Ga S₂, Cu Ga Se₂, Cu Ga Te₂, Cu In S₂, Cu In Se₂, Cu In Te₂, Ag Ga S₂, Ag Ga Se₂, Ag Ga Te₂, Ag In Se₂, Ag In Te₂, using iodine and hydrogen iodide as transporting agents has been reported in this paper. Results give range of temperature for the iodide transport and prevention of starting material formation (elemental transport) in the growth zone. From the range of temperature for the growth of crystals, selected source zone and growth zone temperatures with a differential of 100°C are also listed. Referring the data listed in the tables can grow good quality crystals.
