WebWe identify the critical points (CPs) in the dielectric function spectra of 2D WSe 2 with different layers, and reveal physical origins of the corresponding optical transitions at these CPs by the CP analysis … The hexagonal (P63/mmc) polymorph 2H-WSe2 is isotypic with hexagonal MoS2. The two-dimensional lattice structure has W and Se arranged periodically in layers with hexagonal symmetry. Similar to graphite, van der Waals interactions hold the layers together; however, the 2D-layers in WSe2 are not atomically thin. The large size of the W cation renders the lattice structure of WSe2 more sensitive to changes than MoS2.
