A new workflow uses GW-derived ionization potentials and electron affinities, quasiparticle renormalization for polarization, the integer charge transfer model for pinning, and electrostatic potential shifts to predict adsorbate energy alignment on oxide/metal substrates.
The alignment of the HOMO and LUMO levels (where the IP= 6.61 eV and EA= 1.35 eV), produces a LUMO energy level located at∼1 eV above the Fermi energy

An ab initio approach to energy alignment and charge-state prediction of adsorbates on ultrathin insulators
