Fig. 3. Imaginary parts of dielectric constant along the XX, YY and ZZ tensors as a function of energy for TMDs and their heterostructures with phosphorene. (a) MoS2 (c) MoSe2, (e) MoTe2, (g) WS2 and (i) WSe2. Heterostructures of (b) MoS2/P, (d) MpSe2/P, (f) MoTe2/P, (h) WS2/P and (j) WSe2/P. Dielectric function of phosphorene is shown in (k).
