Effects of AgSnSe2 addition on the thermoelectric properties of Bi0.5Sb1.5Te3

Enhancement of Thermoelectric Properties of p-Type Bi0.4Sb1.6Te3 Incorporated by BaFe12O19 Magnetic Nanoparticles

“…Moreover, taking the anisotropy of the Bi 2 Te 3 -based material into account, the ZT value of BST-1.2 wt % BaFe 12 O 19 along the c -axis exhibits an impressive enhancement, reaching as high as 1.34 at 393 K (Figure S). Figure b illustrates a comparison with other Bi 2 Te 3 -based alloys, ,− indicating superior thermoelectric performance of BST-1.2 wt % BaFe 12 O 19 nanocomposites, particularly in the c -axis direction. The ZT values of BST- x wt % BaFe 12 O 19 nanocomposites can be increased by optimizing the composition of BaFe 12 O 19 nanoparticles.…”
