Faculty Applied Sciences

The Faculty of Applied Sciences is the largest faculty of TU Delft, with around 550 scientists, a support staff of 250 and 1,800 students. The faculty conducts fundamental, application-oriented research and offers scientific education at the bachelor, master and doctoral levels. The faculty is active in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Applied Physics.

The mission of the Department of Chemical Engineering is to generate knowledge and educate people in the area of nano chemical engineering to improve the quality of life for a sustainable society, focusing on energy, water, health and environment.

The Optoelectronic Materials section is part of the Department of Chemical Engineering. Our key interest is studying the nature and dynamics of excited states and charge carriers in molecules, quantum dots, nanorods and two-dimensional materials.   

Job description

You perform computational studies on excitons and charge carriers in semiconducting 2D materials consisting of a metal atom (Mo, W, Nb, Zr, Hf) and a chalcogenide (S, Se, Te). Layers of a single material and bilayers of an electron donor (n-type layer) and an acceptor (p-type layer) are studied. You contribute to analyzing experimental results of  PhD students performing ultrafast pump-probe spectroscopy at TU Delft and the University of Amsterdam (group of prof. Schall). The project is a collaboration with Toyota Motor Europe.

You study band gaps, effective masses, exciton binding energies, as well as mobility and decay kinetics of excitons and charges. Methods to be used include (TD)DFT, GW-Bethe-Salpeter equation, mixed quantum-classical dynamics, implemented in e.g. compute engines in AMS, VASP, GPAW, BerkeleyGW and PYXAID, or home-built codes.   


Candidates must have a PhD degree in physics, chemistry or materials science and have experience with DFT, GW and Bethe-Salpeter calculations.       

Conditions of employment

TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
