Abstract

The present study provides the interface electronic properties between La0.7Sr0.3MnO3 and two archetype organic semiconductors, CuPc and α-6T using a combined X-ray- and ultraviolet photoelectron spectroscopy. La0.7Sr0.3MnO3 is a ferromagnetic metal and can be used to inject spin-polarized current into organic semiconductors. The energy level alignment depends on the cleaning procedure that is applied to the La0.7Sr0.3MnO3 surface prior to deposition of the organic semiconductor.
