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).


We are looking for a talented PhD-student with excellent experimental skills and a curiosity-driven mindset. So, if you are an experimental physicist or a nanoscientist with an affinity for (quantum) charge transport and/or condensed matter physics, feel free to require information and/or to apply.


We offer a full-time one year term position with the possibility of three-year renewal after a positive evaluation. Salary range from € 2,222.- to € 2,840.- gross per month (pay scale P, in accordance with the Collective Labour Agreement for Dutch Universities).

Leiden University offers an attractive benefits package with additional holiday (8%) and end-of-year bonuses(8.3 %), training and career development and sabbatical leave. Our individual choices model gives you some freedom to assemble your own set of terms and conditions. Candidates from outside the Netherlands may be eligible for a substantial tax break.

All our PhD students are embedded in the Leiden University Graduate School of Science http://www.graduateschools.leidenuniv.nl. Our graduate school offers several PhD training courses at three levels: professional courses, skills training and personal effectiveness. In addition, advanced courses to deepen scientific knowledge are offered by the research school.
