Abstract We present a theoretical study of electronic transport in a two-dimensional 8-Pmmn monolayer borophene crystal illuminated by off-resonant electromagnetic radiation within the linear response theory. We find asymmetry in the intrinsic anomalous Hall conductivity of the system, hallmark of anisotropic tilted structure of the Dirac cones in borophene. The width of maximum in the Hall conductivity is of the order of the bandgap in the energy spectrum induced by the radiation. Interestingly, thermal and Peltier conductivities also exhibit pronounced asymmetry in addition to the Hall conductivity of the system. It is shown that such asymmetry in the conductivity originates from the anisotropic tilt in the Dirac cone of borophene. We also find that 8-Pmmn borophene makes transition from type-I to type-II Dirac fermion system in the limit of large tilt parameter.
