· Re4 Te12 Br20

Re4Te12Br20 is a mixed-halide tellurium-based semiconductor compound combining rhenium, tellurium, and bromine elements. This material represents an emerging class of layered halide semiconductors under investigation for optoelectronic and quantum device applications, combining heavy-metal chemistry with tunable band structure properties characteristic of modern perovskite-alternative materials. While primarily in the research phase, compounds in this family are explored for their potential in photovoltaics, photodetectors, and nonlinear optical devices due to their structural flexibility and electronic tunability.
