Quantized thermoelectric Hall plateau in the quantum limit of graphite as a nodal line semimetal
PHYSICAL REVIEW B(2022)
摘要
We performed thermoelectric Hall conductivity $\alpha_{xy}$ measurements on single crystal graphite in the quantum limit up to 13 T. Both electrical and thermoelectric transport measurements were performed on the same crystal to extract pure $\alpha_{xy}$ avoiding any sample quality dependence. The $\alpha_{xy}$ converges to a plateau in the quantum limit with a linear dependence on temperature. This behavior is analogous to the quantized thermoelectric Hall effect (QTHE) observed in 3D Dirac/Weyl nodal point semimetals, and experimentally confirms a theoretical proposal on the QTHE in semimetals with nodal lines like graphite.
