· K4Ge(PSe3)4

K₄Ge(PSe₃)₄ is an inorganic semiconductor compound belonging to the metal phosphide-selenide family, combining potassium and germanium with complex phosphorus-selenium coordination units. This is a research-stage material not yet widely established in commercial production; it represents the broader class of metal chalcogenophosphates being explored for optoelectronic and solid-state device applications where tunable bandgaps and layered structures offer advantages over traditional semiconductors.
