Research Summary: 

Research in LabMonti is focused on obtaining a detailed understanding of interfacial processes in organic electronic devices such as organic photovoltaic cells, organic thermoelectrics or organic spin valves. Interfaces are intrinsically complex environments where two fundamentally different materials meet. As a consequence, the development of solar cells with significantly higher power conversion efficiencies or more efficient spin valves and thermoelectrics presents a major challenge.

Research in LabMonti seeks to elucidate the chemistry and physics of carriers in organic semiconductors at interfaces on the short length- and time-scales present in organic photovoltaic, spin and thermoelectric devices. We probe these interfaces with advanced stead-state and ultrafast photoelectron spectroscopies in our lab and at synchrotrons, and study self-assembly using scanned probe microscopy under highly controlled conditions. We use insights gained from this work also to understand quantum transport in organic semiconductors at the ultimate size limit.
