The PHD candidate will study the mechanism of charge transport through ‘ideal‘ organic layers, by probing electron mobility from the nanoscale to the macroscale.

Two state-of-the-art methods will be combined in this PhD project: a) LEEM (low-energy electron microscopy), and b) single-molecule spectroscopy. Within our LEEM system, the PHD candidate will grow layers of organic molecules with maximal order and minimal trapping (following our ‘lab-inside philosophy'). To investigate their properties, conventional conductance measurements with LEEM-based potentiometry and single-molecule spectroscopy will be combined. The latter will provide dynamical information on the mobility of single electrons. Hence, within the project, the gap between the macro- and nanoscales will be bridget, allowing the PHD candidate to obtain unique information. This unique set of experiments will allow us to test comprehensive model theories for organic electronics. The PHD candidate will be part of both the Van der Molen group (LEEM) and the Orrit team (single-molecule spectroscopy), in Leiden. Support on the theory side is provided by the Blaauboer group (Delft).
