Realizing High Thermoelectric Performance in Earth‐Abundant Bi2S3 Bulk Materials via Halogen Acid Modulation

Bi2S3‐based thermoelectric materials without toxic and expensive elements have a high Seebeck coefficient and intrinsic low thermal conductivity. However, Bi2S3 suffers from low electrical conductivity, which makes it a less‐than‐perfect thermoelectric material. In this work, halogen elements F, Cl,...
