CFN Research Activities

In our research we utilize low-energy electron microscope (LEEM) for the real-time, in situ investigations of the nucleation and growth of thin films. We focus particularly on the  understanding of the self-assembly mechanisms in the organic layers, as they are crucial for the advancement of the organic electronics. LEEM has excellent capability of combining the real-time, real-space observations of the film morphology with the crystallographic analysis by means of micro-beam low-energy electron diffraction (m-LEED). Moreover, use of the low-energy electrons minimizes irradiation damage to the specimen, making this technique especially valuable for studying thin organic films.
