论文摘要
我们研究了经受磁场和潜在的屏障的持续磁场的泥石烯中的狄拉克费烯。分析研究了间隙内的隧道模式和相关的鹅孔（GH）偏移。我们表明，中央频段的传输变化和前两个边带在dirac点$ε+l \ hbar \tildeΩ$ $（l = 0，\ pm 1）$更改标志。我们还发现，GH偏移可能为负或正阳性，并且在传输共振下变为零。
We study Dirac fermions in gapped graphene that are subjected to a magnetic field and a potential barrier harmonically oscillating in time. The tunneling modes inside the gap and the associated Goos-Hänchen (GH) shifts are analytically investigated. We show that the GH shifts in transmission for the central band and the first two sidebands change sign at the Dirac points $ε+l\hbar\tildeω$ $(l=0,\pm 1)$. We also find that the GH shifts can be either negative or positive and becomes zero at transmission resonances.
