K4 Te2 I12
semiconductor· K4 Te2 I12
K4Te2I12 is a layered halide perovskite semiconductor compound combining potassium, tellurium, and iodine elements. This is a research-phase material belonging to the halide perovskite family, which has attracted significant interest for optoelectronic and photovoltaic applications due to their tunable bandgaps and solution-processable synthesis routes. While still in development, materials in this class are being explored as alternatives to lead-based perovskites for solar cells, light-emitting devices, and radiation detection where compositional flexibility and lower toxicity are priorities.
