Thermoelectric properties of Lu-doped n-type LuxBi2-xTe2.7Se0.3 alloys

Lutetium-doped LuxBi2-xTe2.7Se0.3 (x = 0–0.3) nanopowders were synthesized by the hydrothermal method, and then they were hot-pressed into bulk pellets at 773 K under a pressure of 60 MPa in vacuum. The doping effects of Lutetium on the thermoelectric properties were investigated. Compared with the...
