Huge Thermoelectric Power Factor: FeSb2 versus FeAs2 and RuSb2
摘要：
窄禁带半导体FeSb 2的热电功率因数与同结构同系物FeAs 2和RuSb 2相比大大增强。磁性和热力学性质的比较研究提供的证据表明，窄的和相关的带以及相关的增强热电性仅特定于FeSb 2。我们的研究结果指出，在低温下的实际热电应用的潜在的FeSb 2和刺激沿着相同的路线寻找新的相关半导体。
英文摘要：
The thermoelectric power factor of the narrow-gap semiconductor FeSb2 is greatly enhanced in comparison to the isostructural homologues FeAs2 and RuSb2. Comparative studies of magnetic and thermodynamic properties provide evidence that the narrow and correlated bands as well as the associated enhanced thermoelectricity are only specific to FeSb2. Our results point to the potential of FeSb2 for practical thermoelectric application at cryogenic temperatures and stimulate the search for new correlated semiconductors along the same lines.
