Summary: | 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. |
