Summary

Research on ultrathin compounds, particularly transition metal dichalcogenides (TMDs), has gained significant attention due to their unique electronic properties. TMD monolayers, such as MoS2 and WSe2, exhibit direct electronic bandgaps in the visible and near-infrared range, making them promising for nanoelectronics and optoelectronic devices. The weak screening in 2D TMDs leads to the formation of robust excitonic quasiparticles and strong many-body effects, even at room temperature. The band structure of TMDs is characterized by a strong spin-valley coupling, where the valley degree of freedom is coupled with the spin, allowing for the initialization and readout of the electron's valley/spin with polarized light. This unique property enables novel applications in information treatment and makes TMDs an ideal platform for fundamental studies in condensed matter.
