Hg2 I4
semiconductor· Hg2 I4
Hg₂I₄ is a mercury iodide semiconductor compound belonging to the family of heavy metal halides, with a layered crystal structure that exhibits interesting optoelectronic properties. This material is primarily of research interest for radiation detection applications and optoelectronic devices, where its high atomic number and band gap characteristics make it attractive for detecting high-energy photons and particles; however, it remains largely experimental due to toxicity concerns with mercury and the availability of more established alternatives like cadmium telluride and lead halide perovskites for commercial deployments.
