· K2CsSb

K2CsSb is a ternary alkali antimonide compound belonging to the family of photoelectric materials and wide-bandgap semiconductors. This material is primarily of research interest for photocathode applications, where its low work function and efficient electron emission properties make it valuable for devices requiring high quantum efficiency in the ultraviolet to visible spectrum. K2CsSb represents an important material class in modern detection and imaging systems, competing with other alkali antimonide photocathodes by offering improved spectral response and operational stability compared to simpler binary compounds.
