Halogen Acid Modulation In article number 2102838, Zhen‐Hua Ge, Xiaohua Yu, Jing Feng, Jiaqing He, and co‐workers present a new strategy that can significantly improve the electrical transport properties, as well as reduce the lattice thermal conductivity at 673 K in Bi 2 S 3 materials. Due to the optimized electrical conductivity by hydrochloric acid doping during the hydrothermal procedure, nanostructured Bi 2 S 3 with a high ZT value of 0.8 is obtained.
