论文摘要
据报道，在量子大厅效应（QHE）条件下，强烈的鹅 - hänchen（GH）效应。基于对非常规量子厅制度中存在的石墨烯的温度依赖性表面电导率的完整量子描述，可磁性可调的QHE GH移动出现。我们的方法是基于在线性极化光线的KERR相的抗对称电导率张量中得出广义的菲涅尔系数。此外，证明在低温下，GH偏移映射高原，随着磁场的强度的增长。通过施加的磁静态偏置，这种对石墨烯中GH效应的量子调节可能会为光学设备和QHE传感应用在2D材料中的新机会打开大门。
Strong Goos-Hänchen (GH) effect at a prism-graphene interface in the quantum Hall effect (QHE) condition is reported. Based on the full quantum description of the temperature-dependent surface conductivity of graphene present in the unconventional quantum Hall regime, magnetically strong tunable QHE GH shifts emerge. Our approach is based on deriving the generalized Fresnel coefficients with antisymmetric conductivity tensor for the Kerr phase of the incident linearly polarized light. Moreover, it is demonstrated that at low temperatures, GH shifts map plateaus as the intensity of the magnetic field grows. This quantum modulation of the GH effect in graphene by an applied magnetostatic bias may open doors to new opportunities for optical devices and QHE sensing applications in 2D materials.
