For the ELA construction, we neglect energy dispersions and band structure information and just evaluate the VBM (energy at the Γ point) and the CBM (based on optical band-gap measurements taken from literature). The same representation is done with the phthalocyanines as we take the HOMO on-sets and the measured optical band-gap to place the LUMO accordingly. From this, we infer a staggered gap of the frontier orbitals of CoPc with the band edges of MoS2 before contact, i.e. for vacuum level alignment. For CoPcF16 however, we suggest that the VBM and the HOMO are roughly at the same energy before contact. . Green arrows are obtained from UPS measurements at the lab spectrometer (Figures and). Values for the purple arrows are taken from the integrated ARPES measurements (Figures and). Yellow arrows represent the values taken from UV-Vis absorption measurements of the respective phthalocyanine films on glas substrates (Figures and). From Figure , no integer charge transfer from MoS2 to CoPcF16 is expected since the LUMO of CoPcF16 is located above the CB of MoS2, and compared to other electron acceptors the electron affinity is significantly lower. Nevertheless, we find p-type doping of the MoS2. We can deduct that only a new induced gap state at the MoS2/CoPcF16 interface can explain the charge transfer, best described on the basis of the IGS model. We note that the formation of induced gap states at interfaces is known for several organic-metal interfaces and for organicinorganic semiconductor interfaces.
