Bi2SeI2O11
semiconductor· Bi2SeI2O11
Bi2SeI2O11 is a mixed-halide bismuth selenide oxide semiconductor compound combining bismuth, selenium, iodine, and oxygen in a layered crystal structure. This is a research-phase material being explored in solid-state electronics and photonics, where its mixed-anion composition is designed to engineer band gaps and carrier transport properties beyond what single-anion bismuth compounds offer. The material family shows potential for photovoltaic devices, photodetectors, and thermoelectric applications where compositional tuning via halide substitution provides an advantage over conventional semiconductors.
