Hg2I2
semiconductor· Hg2I2
Hg₂I₂ (mercury(I) iodide) is an ionic semiconductor compound belonging to the mercury halide family, characterized by a layered crystal structure with mixed-valence mercury cations. This material is primarily investigated in research contexts for radiation detection and X-ray/gamma-ray spectroscopy applications, where its high atomic number and bandgap properties offer potential advantages over conventional semiconductors, though it remains largely experimental with limited commercial deployment due to stability and purification challenges.
