· Ta6 Se2 I14

Ta6Se2I14 is a layered halide semiconductor compound combining tantalum, selenium, and iodine—a member of the mixed-halide perovskite and transition-metal chalcohalide family. This is a research-phase material studied primarily for optoelectronic and photovoltaic applications where its layered structure and semiconducting properties offer potential advantages in light absorption and charge transport compared to conventional semiconductors. Interest in this compound class stems from tunable bandgaps, solution processability, and the possibility of engineering band structures through composition variation, though real-world deployment remains limited to laboratory prototypes and fundamental studies.
