Magnetic ratchet effect in phosphorene
arXiv:2008.01561 · doi:10.1103/PhysRevB.103.045406
Abstract
The magnetic ratchet effect has been studied in phosphorene by the use of the Boltzmann kinetic equation that is a semi-classical approach. The Hamiltonian of phosphorene in a steady parallel magnetic field is derived using the tight-binding model. We consider the effect of the magnetic field on non--linear dynamics in the presence of an ac laser field and spatial inversion asymmetry. We have shown that for anisotropic 2D materials and phosphorene, the ratchet current has the response to three different light polarizations: linearly polarized light, circularly polarized light, and unpolarized light.
