摘要: A cascade thermoelectric cooler designed to cool cryogenic temperatures of 30 120 K integrates high performance\high-ZT Bi x Sb 2−x Te 3 and 2 3−x Se -based super-lattice-structure thin-film devices with a bulk-material based including plural cascaded cold stages each successive stage able progressively lower temperature. Each in the includes heat source plate, sink p-type thermoelectric, n-type thermoelectric. Moreover, can have multiple which contains super-latticed element, n type element. By bonding an output plate on input cooler, integration bulk-material-based yields wherein cools 160 device between 70 K. Another level super-lattice achieve Alternatively, ZT superlattice multi-staged produce higher performance non-cryogenic cooler.
