Moreover, the renormalized electronic parameters drastically depend on the field polarization. Namely, a linearly polarized field always decreases the band gap (and, particularly, can turn the gap into zero), whereas a circularly polarized field breaks the equivalence of valleys in different points of the Brillouin zone and can both increase and decrease corresponding band gaps. As a consequence, the field can serve an effective tool to control spin and valley properties of the 2D materials and be potentially exploited in optoelectronic applications.012064eninfo:eu-repo/semantics/openAccessElectromagnetic fields2D materialsElectronsSegulmagnRafeindirinfo:eu-repo/semantics/articleJournal of Physics: Conference Series10.1088/1742-6596/1461/1/012064
