abstract

  • A theoretical study on the rise of photo-oscillations in the magnetoresistance of hexagonal boron nitride (hBN)-encapsulated graphene is presented. The previous radiation-driven electron orbit model devised to study the same oscillations, well-known as MIRO, in 2D semiconductor systems (GaAs/AlGaAS heterostructure) is used. It is obtained that these graphene platforms under radiation and a static magnetic field are sensitive to terahertz and far-infrared radiation. The power, temperature, and frequency dependences of the photo-oscillations are studied. For power dependence, it is predicted that for cleaner graphene and high enough power it is possible to observe zero-resistance states and a resonance peak.
