KAgSe is an intermetallic compound composed of potassium, silver, and selenium that belongs to the class of layered metal chalcogenides. This is primarily a research material studied for its potential in electronic and photonic applications, particularly in contexts where two-dimensional or quasi-2D behavior is desirable; it is not currently produced at commercial scale for industrial applications. The material's layered crystal structure and relatively low exfoliation energy suggest promise for applications in thermoelectric devices, optoelectronic components, or as a precursor phase in advanced semiconductor research, though practical engineering adoption remains limited to specialized academic and exploratory industrial R&D settings.
