用Slonczewski-Weiss- McClure三维能带结构计算对石墨低温磁输运的一致性解释
A consistent interpretation of the low temperature magneto-transport in graphite using the Slonczewski--Weiss--McClure 3D band structure calculations
摘要：
在mK温度下测量了天然石墨和高取向热解石墨（HOPG）的磁输运。在轨道角动量量子数达到$N\approx90$的情况下，观察到电子和空穴载流子的量子振荡。一个显着的协议时，得到的数据和预测的Slonczewski-Weiss-McClure紧束缚模型的大规模费米子比较。在输运数据中没有观察到狄拉克费米子的证据，输运数据主要由费米能级的朗道带交叉所支配，对应于$dE/dk_z=0$，它发生在远离预期狄拉克费米子的$H$点的地方。
英文摘要：
Magnetotransport of natural graphite and highly oriented pyrolytic graphite (HOPG) has been measured at mK temperatures. Quantum oscillations for both electron and hole carriers are observed with orbital angular momentum quantum number up to $N\approx90$. A remarkable agreement is obtained when comparing the data and the predictions of the Slonczewski--Weiss--McClure tight binding model for massive fermions. No evidence for Dirac fermions is observed in the transport data which is dominated by the crossing of the Landau bands at the Fermi level, corresponding to $dE/dk_z=0$, which occurs away from the $H$ point where Dirac fermions are expected.
