CsInGeS4
semiconductor· CsInGeS4
CsInGeS4 is a quaternary chalcogenide semiconductor compound combining cesium, indium, germanium, and sulfur elements. This material belongs to the family of wide-bandgap semiconductors and is primarily investigated in research contexts for infrared optics and nonlinear optical applications. The sulfide-based composition positions it as a candidate for mid-infrared transmission windows and frequency conversion devices, where it competes with established alternatives like ZnSe and GaAs in specialized spectral regions.
