· Na0.5Pb1.75GeSe4

Na0.5Pb1.75GeSe4 is a mixed-cation lead germanium selenide compound belonging to the family of chalcogenide semiconductors. This is a research-stage material under investigation for thermoelectric and solid-state energy conversion applications, where its layered crystal structure and mixed-valence composition are expected to provide low thermal conductivity and tunable electronic properties. The compound represents an emerging class of earth-abundant alternatives to conventional thermoelectrics, with potential relevance to waste heat recovery and solid-state cooling systems where cost and scalability are drivers alongside performance.
