Response of the monolayer molybdenum disulfide to external circularly and/or elliptically polarized electromagnetic fields

Based on the intersubband transition theorem of the semiconductors, we have theoretically investigated the optical dielectric function, absorption spectrum, and reflectivity of the monolayer molybdenum disulfide ( $$\hbox {MoS}_2$$ ) under the irradiation of a circularly and/or elliptically polarized light. The resonance frequency of the absorption spectrum and reflectivity has been observed to be same with that of the real and imaginary part of the dielectric functions, while the amplitude of the resonance peaks becomes higher with the increase of the amplitude ratio of the polarized light. The monolayer $$\hbox {MoS}_2$$ should be more sensitive to the linearly polarized electromagnetic fields, especially to the transversally polarized light. The obtained results may be useful in the design of the spintronic and optoelectronic devices based on $$\hbox {MoS}_2$$ .
