| 2 | Screening for new thermoelectric material: A semiconducting TaS_(3) with nanoporous structure显示文摘Transition-metal sulfides,such as 1T-and 2H-TaS_(2),are attracting considerable interest in modern condensed matter physics for their diverse behaviors of the Mott state,peculiar charge-density-wave phase and superconductivity.The intrinsically low thermal conductivities along the cross-plane direction can advantage the potential high thermoelectric performance;yet,their insignificant power factors severely hampered the practical applications as thermoelectric devices.In this perspective,we herein present a new semiconducting phase in TaS_(3) with the space group C2/m predicted by the swarmintelligence structure-searching method.The C2/m-TaS_(3) phase exhibits anisotropic multivalley band dispersions,which is beneficial for electronic transport.Meanwhile,the unique structure within nanopores leads to strong anharmonic scattering,significantly reducing the lattice thermal conductivity.As a result,the calculated figure of merit ZT can reach up to 1.68 and 1.57 at 800 K for p-and n-type,respectively that is comparable with conventional thermoelectric materials(e.g.PbTe,Bi_(2)Te_(3)).Therefore,our calculation reveals that the C2/m-TaS_(3) phase can be a potential high-performance candidate as nontoxic and eco-friendly thermoelectrics,and will stimulate further experimental exploration for understanding and tailoring thermoelectric capability in related transition-metal sulfides. | Yangfan Cui Xiaojun Wang Shuai Duan Xin Chen Xiaobing Liu | 2022 | Journal of Materiomics2022，8，5： | 1 |
