The invention belongs to the field of materials, and discloses a method for improving the thermoelectric performance of SnTe through Zn doping. Sn powder, Zn powder and Te powder are respectively weighed according to the element ratio of 1-x:x:1, wherein the value of x is 0.01-0.05 , Grind, mix and evenly press into a sheet, put it into a quartz tube, vacuumize and seal the tube, and sinter in a box furnace and a discharge plasma sintering furnace in turn to obtain a Zn-doped SnTe compound thermoelectric material. The method of the invention has simple process operation and high repeatability, and the prepared SnTe-doped Zn compound has the characteristics of high crystallinity, less impurities, high density and the like, and can greatly improve the performance of the SnTe thermoelectric material. |
