Enhanced thermoelectric performance of n-type TiCoSb half-Heusler by Ta doping and Hf alloying

Organic/Inorganic Hybrid Design as a Route for Promoting the Bi0.5Sb1.5Te3 for High‐Performance Thermoelectric Power Generation

“…Since the total thermal conductivity (κ) is the sum of the electronic thermal conductivity (κ e ), lattice thermal conductivity (κ Latt ), and bipolar thermal conductivity (κ B ), [53] we calculated 3b). [54,55] With the increase of CuPc content, the overall (κ Latt + κ B ) of the BST/CuPc x composites decreased significantly.…”

Electronic structure and low-temperature thermoelectric transport of TiCoSb single crystals

“…High resistivity values result in 0.15 mW cm -1 K -2 for Batch 2, whereas batch 1 shows 2.0 mW cm -1 K -2 at room temperature. Despite the undoped composition, the latter one is comparable to that of optimized half-Heuslers with high thermoelectric performance at high temperatures 55,56 . Thus, it is another indication of the band convergence effect on the high-performance p-type TiCoSb derivatives.…”

Advances in half-Heusler alloys for thermoelectric power generation

“…These studies have also shown that n-type TiCoSb is substantially more promising than its p-type counterpart, 139 with the composition Ti 0.6 Hf 0.3 Ta 0.1 CoSb reaching zT 973 K = 0.9. 143 A subsequent study on (Hf 0. size. 100 This leads to semiconducting behaviour near 300 K, while at high temperatures degenerate semiconducting behaviour is observed.…”
