论文摘要
如证明，在波纹石墨烯超级晶格中插入带隙$δ$可导致新的结果。重要的是外观相反的自旋传输，随着$δ$而增加，而没有它就会消失。此外，与$δ= 0 $方案相比，具有相同自旋的变速箱抑制时间更长，有许多峰。具有相同自旋的传输的最大值降低并保持在统一附近。此外，对于特定的能量值，发现传输通道行为的变化。结果，我们证明，使用$δ$，传输过滤变得至关重要。最后，由于带隙，发现了总电导率的不同变化。
The insertion of the band gap $Δ$ in the rippled graphene superlattice leads to new outcomes, as demonstrated. The essential thing is the appearance of opposite-spin transmissions, which increase with $Δ$ and vanish without it. Furthermore, compared to the $Δ=0$ scenario, the duration of the suppression of the transmission with the same spin is longer, with many peaks. The maximum value of transmissions with the same spin declines and remains around unity. Furthermore, for particular energy values, a shift in the behavior of the transmission channels is found. As a result, we demonstrate that with $Δ$, transmission filtering becomes crucial. Finally, as a result of the band gap, distinct variations in total conductance are discovered.
