Scheele group: Coupled Hybrid Nanostructures

The independent junior research group of Marcus Scheele at the IPTC is concerned with the bottom-up synthesis of colloidal nanoparticles (mainly IV-VI and II-VI semiconductors but metals as well), the surface functionalization of these particles with organic semiconductors, and their self-alignment in meso-crystalline thin films and three-dimensional superlattices. In field-effect transistors these hybrid semiconducting nanostructures are analyzed for charge carrier concentration, mobility, and type of majority carriers, at which the central aspect is the coupling of energy levels of the nanoparticle to suitable molecular orbitals of the organic semiconductor. The optical properties of these materials, e.g. fluorescence and lifetime, are studied in cooperation with the Meixner research group.
