Interlayer excitons (ILEs) involving an electron and a hole situated in separate adjacent layers are pronounced intype-IITMD-based heterobilayers. Tebyetekerwa etal. report a high twist-angle-dependent energy shift of the ILE emission peak in MoS2/WS2heterobilayers for different samples investigated ...
Theoretical and first-principal studies involving twisted two-dimensional (2D) heterobilayer transition metal dichalcogenides (TMDs) predict interlayer exciton (ILE) emission energy amplitudes (the energy difference between the lowest and the highest ILE emission energies) in the range of 100-260 meV. ...
In the bilayer, stacking of the WS2 layer is expected to lead to a red shift of MoSe2 A exciton resonance18 while also introducing an interlayer exciton transition, between an electron in WS2 and a hole in MoSe2. The interlayer exciton has a negligible oscillator strength and should not be...

In addition, for MoS2/WS2 with θ ≈ 1.8° and MoSe2/WSe2 with θ ≈ 2.4° the energy profile for interlayer interband exciton resembles an antidot superlattice more than an array of QDs. This contrasts with the persistence up to θ ~ 3.5° of shallow QD arrays for both...
Vertical and in-plane heterostructures from WS2/MoS2 monolayers A strong interlayer excitonic transition is observed due to the type II band alignment and to the clean interface of these bilayers. Vapour growth at low temperature, on the other hand, leads to lateral epitaxy of WS2 on MoS2 edges...
