Job description

Colloidal nanocrystals (NCs) have become an established semiconductor material with applications in opto-electronics, nanophotonics and quantum technologies. NCs combine a suitability for solution-based processing with tunable materials properties, for example through the NC size or dimensionality (0D, 1D, 2D). Such characteristics have a direct impact on the behavior of elementary excitations, electron-hole pairs or excitons, created in such NCs by light absorption. Understanding the different exciton states, i.e., the exciton fine structure (EFS), is a key factor for successful application development.

In the CONEX project, we aim at utilizing the latest generation of NCs to extend the understanding of EFS towards new materials (III-V vs II-VI NCs) and explore the impact of dimensionality (2D vs. 0D), crystallinity (zinc blende vs. wurtzite) and the NC surface on exciton properties.

To achieve these goals, we are looking to expand our team with a Ph.D. student who will focus on the synthesis of III-V NCs, characterization of NC ensembles and individual NCs using both ultrafast laser spectroscopy and cryogenic microscopy, and the development of the theory of excitons in III-V QDs. For the latter, we will work together intensively with researchers at the IOFFE institute (Russia).

Profile of the candidate

The Ph.D. candidate must hold a master degree in physics, chemistry, or materials science, and show a strong interest in photonic nanomaterials and advanced optical spectroscopy. The degree should be obtained before the prospective starting date of April 1st 2020. The Ph.D. candidate will be offered a 2-year scholarship, renewable up to a maximum duration of four years. The work will be executed in the Physics and Chemistry of Nanostructures Group at Ghent University, Belgium (www.nano.ugent.be)
