Microstructural iterative reconstruction toward excellent thermoelectric performance in MnTe

Abstract

Earth-abundant manganese telluride (MnTe) with a hexagonal structure has shown significant thermoelectric conversion potential; however, the drawbacks of low carrier concentration and low mobility have limited its application. Herein, we...

Off‐Centering of Ge Atoms in GeBi2Te4 and Impact on Thermoelectric Performance

“…[30][31][32][33] Consequently, there has been an emphasis on investigating the thermoelectric capabilities of layered compounds derived from (Bi,Sb) 2 (Te,Se) 3 -based alloys. [34][35][36][37][38] For instance, In doped Ge 2 Sb 2 Te 5 exhibits a high ZT of 0.78 at 700 K, [39] and the configurational entropy has been quantified in relation to thermal conductivity in GeSb 2 Te 4 . [40] However, compared to nGeTe-mSb 2 Te 3 , the thermoelectric properties of nGeTe-mBi 2 Te 3 , such as GeBi 2 Te 4 , have received less attention, despite its tunability to exhibit both p-type and n-type transport.…”

Boosting the thermoelectric performance of Yb-filled skutterudites through the incorporation of YSb nanoprecipitates

“…5–10 Although the high power factor ( S 2 σ ) and the low κ are beneficial for reducing self-loss and maintaining a desirable temperature gradient during energy conversion, the interdependent nature of TE parameters creates a challenging scenario when trying to enhance the ZT value of TE materials. 11,12 Consequently, it is crucial to subtly adjust these property factors.…”

Realizing high-performance thermoelectric modules through enhancing the power factor via optimizing the carrier mobility in n-type PbSe crystals

“…These strategies encompass manipulations of the band structure to bolster electrical transport properties 9–11 or the design of defect structures to reduce thermal conductivity. 12–14 However, these aforementioned strategies inevitably lead to a deterioration in carrier mobility, a critical factor closely tied to the power factor. This, in turn, poses a constraint on the ultimate enhancement of thermoelectric performance.…”
