KNbCu2Se4
metal· JVASP-86939· KNbCu2Se4
KNbCu2Se4 is a ternary metal selenide compound combining potassium, niobium, and copper elements in a layered crystal structure. This is a research-phase material studied for its potential electronic and thermoelectric properties rather than an established commercial alloy; compounds in this family are of interest for solid-state device applications where layered metal chalcogenides offer tunable electrical and thermal characteristics.
