K2 Ge2 Br6
semiconductor· K2 Ge2 Br6
K₂Ge₂Br₆ is an inorganic halide perovskite semiconductor compound composed of potassium, germanium, and bromine. This material belongs to the emerging family of lead-free halide perovskites under active research for optoelectronic applications, offering potential advantages in stability and toxicity compared to lead-based alternatives. While primarily in the research and development phase, K₂Ge₂Br₆ and related germanium halides are investigated for photovoltaic devices, X-ray scintillators, and radiation detection due to their semiconducting properties and relatively high atomic number composition.
