Abstract

We have investigated the pristine alkali metal doping effect which is the Fermi level of alkali metal doped Alq3 shifts toward the LUMO. In-situ measurements of synchrotron radiation photoelectron spectroscopy revealed that the interface dipole or bend bending in previous reports are not the pristine alkali metal doping effect
