Tunable spin hall effect via hybrid polaritons around epsilon-near-zero on graphene-hBN heterostructures
We present a tunable spin Hall effect of light (SHEL) by introducing a monolayer of graphene on the hexagonal boron nitride (hBN).The interaction between the phonon polaritons in hBN and the plasmon polaritons in graphene Roller Skate Gear can significantly enhance the SHEL around epsilon-near-zero (ENZ) near reststrahlen band-I (RB-I) in a very wi
