Calculated evolution of the excitonic energy landscape under the influence of the electric field. The color scale corresponds to the spatial character of the excitons i.e. intralayer (blue), hybrid (purple) or interlayer (red). The opaque (semi-transparent) lines correspond to the spin-singlet (spin-triplet) states. The bottom energy scales ( E − E 0 ) in panels c and d are shown with respect to the A 1s exciton energy E 0 = 1.606 eV.
