Tuning hybrid molecule/magnetic interfaces by defect engineering (A02)

• Subject Area: Experimental Condensed Matter Physics ; Polymer Materials
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 465145163

Doping systems of small molecules and polymers with additives has been shown to be a highly efficient method for varying the charge carrier density over multiple orders of magnitude. Here, we aim to investigate the impact of doping on the spin transport mechanisms in organic semiconductors by probing the change in the effective spin-to-charge conversion efficiency. Furthermore, we will study the effect of defect engineering on the hybridization at the interface between the molecules and metallic thin films by probing the magnetic properties using a combination of electrical magneto-transport experiments and magnetic imaging techniques.
