WebThe increased effective dielectric screening in the WS 2 /MoS 2 heterostructure weakens the long-range Coulomb force between electrons and holes. Consequently, the quasi-particle band gap and the exciton binding energies are reduced, and because of the orbital overlap, more CPs are produced in the WS 2 /MoS 2 heterostructure in the high photon ... WebThe correct option is D Less than p− electrons. More diffused is the shape of the orbitals poorer is the screening effect. s- spherical shape. p- dumbbell. d- double dumbell. f- complex. Since s orbital is spherical in shape thus it is most penetrating. Hence,the order of screening effect is s >p >d >f. Suggest Corrections.
