Thermoelectric effects and topological insulators [PDF]
Chinese Physics B, 2016 The recent discovery of topological insulator (TI) offers new opportunities for the development of thermoelectrics, because many TIs (like Bi$_2$Te$_3$) are excellent thermoelectric (TE) materials. In this review, we will first describe the general TE properties of TIs and show that the coexistence of the bulk and boundary states in TIs introduces ...

Advanced Engineering Materials, EarlyView.Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...
