论文摘要
理论和实验研究支持$α$ - （bedt-ttf）$ _ 2 $ i $ _3 $在压力下的电子结构由二维Dirac Fermions描述。当层间隧穿相干时，系统的电子结构将变为三维，我们预计峰结构将出现在磁场下的层间电阻率中。我们从理论上和实验表明，在低温和高磁场下，峰出现在层间电阻率中。从实验中，我们估计层间隧道的大小为$ T_1 \ SIM 1 $ MEV。我们的结果打开了调查$α$ - （BEDT-TTF）$ _ 2 $ i $ _3 $的三维电子结构的大门。
Theoretical and experimental studies have supported that the electronic structure of $α$-(BEDT-TTF)$_2$I$_3$ under pressure is described by two-dimensional Dirac fermions. When the interlayer tunneling is coherent, the electronic structure of the system becomes three-dimensional, and we expect the peak structure to appear in the interlayer resistivity under magnetic fields. We theoretically and experimentally show that the peak appears in the interlayer resistivity at low temperatures and high magnetic fields. From the experiment, we estimate that the magnitude of the interlayer tunneling is $t_1 \sim 1$ meV. Our result opens the door to investigating the three-dimensional electronic structure of $α$-(BEDT-TTF)$_2$I$_3$.
