Nanostructuring of organic radicals on hybrid interfaces — •Arkaprava Das, Ewa Malgorzata Nowik-Boltyk, Tobias Junghoefer, and Maria Benedetta Casu — Institute of Physical and Theoretical Chemistry, University of Tübingen, 72076 Tübingen, Germany
Organic radicals are potential candidates for groundbreaking applications like energy storage, quantum computing, and spintronics. In order to investigate the nature of the adsorption of the radical derivative molecules on hybrid surfaces based on polycrystalline Au and native SiO2, we investigate their electronic structure and morphology. The electronic structure at the interface is investigated by using X-ray photoelectron spectroscopy (XPS) and the morphology is studied with scanning electron microscopy. The substrate-dependent interface interactions have resulted in different nanostructures crucial for device fabrication whereas changes in line shape of core level spectra confer direct evidence of changed electronic properties.
