论文摘要
研究了具有直线线的淋巴线半学的高磁场热电效应。三维（3D）DIRAC/WEYL半法在高磁场量子限制下表现出恒定的热电霍尔电导率，从而导致Seebeck系数的无限线性增加。这被称为量化热电厅效应（QTHE），预计在低温下会导致高性能热电学。在这里，除了Dirac/Weyl半法外，我们还证明了具有直线线的3D半学也可以在高磁场下显示Q。作为实验验证的候选材料，我们讨论了散装石墨的热电特性。此外，我们研究了薄膜石墨中热电学对二维行为的尺寸交叉。
The high-magnetic-field thermoelectric effect in nodal-line semimetals with straight nodal lines was investigated. Three-dimensional (3D) Dirac/Weyl semimetals exhibit constant thermoelectric Hall conductivity at the high-magnetic-field quantum limit, resulting in a boundless linear increase of Seebeck coefficient. This is known as the quantized thermoelectric Hall effect (QTHE), and is expected to lead to high-performance thermoelectricity at low temperatures. Here, in addition to Dirac/Weyl semimetals, we demonstrated that 3D semimetals with straight nodal lines can also exhibit the QTHE under high magnetic fields. As a candidate material for experimental validation, we discussed the thermoelectric properties of bulk graphite. Furthermore, we investigated the dimensional crossover of thermoelectricity to two-dimensional behavior in thin-film graphite.
