InGaSe2 is a new infrared (IR) grade semiconductor with vdW layered structure. Theoretical studies suggest narrow (0.5 eV) bandgap value while the experimental investigations still remain limited to date. Our InGaSe2 vdW crystals were synthesized using chemical vapor transport technique (CVT) at 99.999% or higher purity values. The materials are highly crystallized and exhibit high optical and electronic performance. Typical crystals measure 4-6mm in size.
