· K4In4P6Se20

K4In4P6Se20 is a quaternary semiconductor compound composed of potassium, indium, phosphorus, and selenium, belonging to the family of metal phosphide selenides. This material is primarily of research interest for its potential optoelectronic and photovoltaic applications, as compounds in this family are being explored for tunable bandgap properties and non-linear optical behavior. Engineers and materials researchers investigate such quaternary chalcogenides for next-generation solar cells, infrared detectors, and quantum dot applications where compositional flexibility offers advantages over binary or ternary semiconductors.
