| Abstract | The introduction of entropy concept into thermoelectric materials recently has attracted broad interest. Herein, we showed the phase diagram of the ternary systems of Bi2Se3–Sb2Se3–In2Se3. Among the high entropy compounds (HECs), we have identified an intrinsic p-type region near our previously reported Bi0.8Sb0.8In0.4Se3 in the phase diagram. We then conducted a systematic investigation in the intrinsic p-type HECs of Bi0.8−xSb0.8In0.4 + xSe3 (x = −0.1 – 0.4), identifying the evolution of real-space lattice structure and reciprocal-space energy band structure. A peak ZT value of 0.68 is achieved in Mn0.03Bi0.67Sb0.8In0.5Se3 at 500 °C, a new record in the p-type Bi2Se3 family. |
