Abstract: Provided is a monatomic amorphous palladium, a method for preparing the same and use thereof. The method comprises a) loading a monatomic palladium powder on a silicon nitride substrate; b) heating the silicon nitride substrate loaded with the monatomic palladium powder obtained in a) up to a temperature of 800° C. to 1000° C. and keeping the temperature for at least 3 minutes; and c) cooling a system of palladium and silicon nitride obtained in b) to room temperature at an apparent cooling rate greater than 103° C./second, thus obtaining the monatomic amorphous palladium.

Abstract: Disclosed are a high performance thermoelectric device and a method of manufacturing the same at ultra-high speed. The high performance thermoelectric device includes segmented structures which may provide an optimal match between the thermoelectric materials and the environmental temperature difference; blocking layers and stress-buffering layers which can reduce interface element migration and longitudinal contact thermal expansion stress and increase bonding strength; phonon scattering layers and negative thermal expansion buffering layers inserted and fixing the thermoelectric leg, thereby increasing internal thermal resistance and improving transverse thermo-match for the high performance thermoelectric device; an inner package and an outer package, thus avoiding sublimation and oxidation of the thermoelectric materials and providing the thermoelectric device with enhanced impact resistance from outside.
