KInGeS4
semiconductor· KInGeS4
KInGeS₄ is a quaternary semiconductor compound composed of potassium, indium, germanium, and sulfur, belonging to the family of ternary and quaternary chalcogenides. This material is primarily of research interest for optoelectronic and photovoltaic applications, where its direct bandgap and layered crystal structure offer potential advantages in light emission, detection, and energy conversion; it represents an emerging class of wide-gap semiconductors being explored as alternatives to conventional III-V and II-VI compounds for specialized photonic and thermoelectric devices.
