Sr2 Ca2 I8
semiconductor· Sr2 Ca2 I8
Sr₂Ca₂I₈ is a halide perovskite semiconductor compound combining strontium, calcium, and iodine in a layered crystal structure. This material is primarily of research interest rather than established commercial use, investigated for optoelectronic applications where its bandgap and electronic properties may offer advantages in light emission, detection, or photovoltaic devices compared to lead-based halide perovskites. Engineers evaluating this compound should recognize it as an emerging material in the halide perovskite family, with potential relevance to next-generation semiconductor devices seeking lead-free or toxicity-reduced alternatives.
