KSb5S8
semiconductor· KSb5S8
KSb₅S₈ is a quaternary sulfide semiconductor compound combining potassium, antimony, and sulfur in a layered crystal structure. This material belongs to the family of metal chalcogenides and is primarily investigated in research settings for optoelectronic and energy conversion applications due to its tunable bandgap and potential for efficient light absorption. Its anisotropic crystal structure and relatively high charge carrier mobility make it of interest for next-generation photovoltaic devices and infrared detectors, though commercial applications remain limited compared to more established semiconductors.
