论文摘要
我们报告了增强的层间隧道，并在零层中偏置的线宽减少，在量子厅制度中的扭曲控制的双单层石墨烯异质结构中，当顶部（$ v _ {\ v _ {\ mathrm {t}}} $）和底部（$ν_ {\ mathrm {t} $）和（$ν_ $ν_ {\ mathrm {t}} = \ pm1/2，\ pm3/2 $和$ν_ {\ mathrm {b}} = \ pm1/2，\ pm3/2 $，以及总填充因子$ν= \ pm1 $或$ \ pm3 $。零偏置层间电导峰在层填充因子的变化方面是稳定的，并信号是层间相干性的出现。我们的结果强调了扭曲控制是使用隧道揭示层间相干性的关键属性。
We report enhanced interlayer tunneling with reduced linewidth at zero interlayer bias in a twist-controlled double monolayer graphene heterostructure in the quantum Hall regime, when the top ($ν_{\mathrm{T}}$) and bottom ($ν_{\mathrm{B}}$) layer filling factors are near $ν_{\mathrm{T}}=\pm1/2, \pm3/2$ and $ν_{\mathrm{B}}=\pm1/2, \pm3/2$, and the total filling factor $ν= \pm1$ or $\pm3$. The zero-bias interlayer conductance peaks are stable against variations of layer filling factor, and signal the emergence of interlayer phase coherence. Our results highlight twist control as a key attribute in revealing interlayer coherence using tunneling.
