Intrinsically Low Thermal Conductivity in BiSbSe3: A Promising Thermoelectric Material with Multiple Conduction Bands Thermoelectric technology that can directly and reversibly convert heat to electrical energy has received wide attention due to global energy and environmental demands. But the application of TE technology is limited by the low power generation conversion efficiency which is determined by the dimensionless figure of merit ZT. An efficient TE material needs high power factor and low thermal conductivity. However, the complex interrelation among these parameters makes it difficult to improve the overall efficiency. To date, many emerging methods have been effectively employed to optimize final ZTs. As one narrow bandgap semiconductor, Bi2Te3 possesses excellent electrical conductivity and Seebeck coefficient, and thus it is one of classic room-temperature TE materials. ZTs for both n-type and p-type Bi2Te3-based systems are larger than unity, which have been widely applied for TE power generation and electronic cooling around room temperature for several decades. It is well known that Te is a scarce element in the crust of the earth, additionally, the cost of Te would rise sharply along with the Te-containing TE materials reach mass markets. A broad search for inexpensive alternatives is therefore warranted. In this case, the Te-free TE materials have attracted huge interest. As a sister compound of Bi2Te3, Bi2Se3 has drawn little attention due to its inferior TE performance. In this work, to improve the TE performance of Bi2Se3, we introduced Sb substitutions on Bi sites. Interestingly, BiSbSe3 has extremely low thermal conductivity, which is related to the phase transition from the rhombohedral structure of Bi2Se3 to the orthorhombic structure of Sb2Se3. Therefore, it is expected that BiSbSe3 could display a promising TE performance after optimizing carrier density via electrons doping. Here, we aimed at investigating the origins of the low thermal conductivity of BiSbSe3, and found that BiSbSe3 possesses very low elastic properties and large Grüneisen parameter γ, related to its strong anharmonicity caused by lone-pair electrons come from Sb/Bi in BiSbSe3. These experimental results are well supported by theoretical calculations on phonon dispersions. Additionally, the multiple conduction bands of BiSbSe3 imply a possibility to improve the electrical transport properties by manipulating these bands through introducing a higher density of electron carriers. Our results show the carrier density can be increased through Br doping, which could activate Fermi electron pockets and enhance Seebeck coefficients. Finally, we obtained a ZT ∼ 1.4 at 800 K due to enhanced power factor and favorable thermal conductivity, the superior performance of BiSbSe3 is competing with most of the state-of the-art medium-temperature n-type TE materials.
