Abstract:
We study Klein tunneling across a PN junction in monolayer graphene (MLG) and the AB-bilayer graphene (BLG) under the effect of a perpendicular magnetic-field (B-field). In the Klein tunneling process, normally incident electrons in MLG (BLG) are fully transmissive (reflective) upon hitting the junction barrier. When a finite B-field is applied, transmission of the normally incident electrons is suppressed in MLG over an energy range around the PN barrier height, effectively opening an energy gap. This suppression may be attributed to the magnetic deflection arising from Lorentz force, which shifts the transmission profile of the device in the transverse direction.
