During this project you will develop and exploit an experimental setup able to measure the spatial diffusion of photo-excited electron-hole pairs (excitons) within new types of photovoltaic nanomaterials. For basic characterization of the optical response of these materials you will use polarization-resolved and time-resolved photoluminescence experiments, as well as fluorescence line narrowing experiments. Exciton diffusion, which is a key parameter in the efficiency of photovoltaic cells, will be determined by a photoluminescence imaging technique. These experiments will be carried out in magnetic fields up to 38 T to unravel possible effects of the exciton spin on the photovoltaic response.

You will actively cooperate with other PhD students and postdocs of HFML working on related topics and you will be involved in helping external users carry out related experiments in high magnetic fields.

We seek talented, enthusiastic and motivated candidates with a Masters' degree in (Solid State) Physics or related subject areas.

Experience with (time-dependent) optical experiments and low-temperature techniques is welcome though not mandatory.

Fixed-term contract: four years.

When fulfilling a PhD position at NWO-I, you will get the status of junior scientist. 
You will have an employee status and can participate in all the employee benefits NWO-I offers. You will get a contract for four years. Your salary will be up to a maximum of 2,834 euro gross per month. The salary is supplemented with a holiday allowance of 8 percent and an end-of-year bonus of 8.33 percent. You are supposed to have a thesis finished at the end of your four year term with NWO-I. 

A training programme is part of the agreement. You and your supervisor will make up a plan for the additional education and supervising that you specifically need. This plan also defines which teaching activities you will be responsible (up to a maximum of ten percent of your time). The conditions of employment of NWO-I are laid down in the Collective Labour Agreement for Research Centres (Cao-Onderzoekinstellingen), more exclusive information is available at this website under Personeelsinformatie (in Dutch) or under Personnel (in English).

General information about working at NWO-I can be found in the English part of this website under Personnel. The 'Job interview code' applies to this position.

Radboud University Nijmegen

HFML is an international research facility, jointly run by Radboud University and FOM. We use and develop high magnetic fields and state-of-the-art instrumentation to carry out pioneering research by both in-house and external users in the fields of Semiconductors & Nanostructures, Correlated Electron Systems and Soft Condensed Matter & Nanomaterials.
