Polarons Imaged in Real Space by Combined AFM/STM

Polarons [1] are quasiparticles that form in ionic lattices due to the interaction of excess charges with lattice distortions. This leads to a spatial confinement of the charge and appearance of many novel phenomena. In past decades, polarons turned out to play an important role in electrical transport, optical properties, organic electronics, catalysis, or in exotic materials properties such as colossal magnetoresistance or high-Tc superconductivity.

A mechanistic understanding of the dissociation of O2 molecules adsorbed on metal surfaces is crucial not only for the precise control of oxidation reactions but also for the development of various heterogeneous oxidation catalysts. [more]

Multilayer supramolecular architectures at device interfaces: Prospects for electron and phonon transport

Manufacturing atomically-precise functional nanoarchitectures with tailored physics at well-defined device interfaces is a frontier in bottom-up nanomaterial [1,2] and condensed matter design [3]. A long-standing challenge in the field is the integration of functional elements in proof-of-concept devices. One strategy to alleviate the cumbersome device integration of single-layered molecular systems, is to achieve increasing control over vertical supramolecular heterojunctions and multilayers, so as to transition from ‘on-surface’, to ‘out-of-surface’ surface science protocols.
