KBaSbSe3

KBaSbSe3 is a ternary halide semiconductor compound containing potassium, barium, antimony, and selenium, belonging to the family of layered perovskite-like chalcogenide materials. This compound is primarily of research and development interest for infrared optics and nonlinear optical applications, where its wide bandgap and strong light-matter interactions make it a candidate for mid-to-long wavelength photonic devices; it represents an emerging class of materials being explored to replace traditional semiconductors in specialized optoelectronic niches where conventional materials (germanium, InSb) face performance or cost limitations.
