Job description

In the PHOCONA project, we aim to develop a new class of highly fluorescent 2D and quasi-2D colloidal nanomaterials for solution-processed coherent light sources and ultrafast single-photon emitters. The materials will consist of suspended semiconductor nanoplates with a thickness below 5 nm, and transition-metal dichalcogenide monolayers. Prepared by colloidal chemistry or, in the latter case, also liquid-phase exfoliation, they take advantage of both quantum confinement through their nanoscale dimensions, as well as dielectric confinement via the dielectric mismatch between nanomaterials and surrounding host. With smart nanocrystal design, the nanomaterials will be shaped toward efficient multiexciton and stimulated emission, as well as stable, blinking-free single-photon emission. The intrinsic optoelectronic properties will be further modified toward ultrafast exciton recombination by coupling the nanomaterials to small mode-volume plasmonic nanocavities, hereby placing them in a local photon density-of-states that will lead to a strong Purcell enhancement

Profile of the candidate

The PHOCONA team in the Physics and Chemistry of Nanostructures Group is currently synthesizing a range of 2D materials, and we are now looking for a postdoctoral researcher that will investigate the optoelectronic properties and carrier dynamics on ensemble and single-dot level. Using time-resolved fluorescence and absorption spectroscopy, you will investigate the materials and steer them toward ultrafast emission lifetimes, single-photon emission, or suppressed linear (trapping) and nonlinear (Auger) recombination losses and efficient optical gain. The optimized emitters will be used as quantum or coherent light sources throughout the project, and insights gained via optical spectroscopy will in turn guide the synthesis of 2D nanomaterials.

How to apply

The applicant must hold a Ph.D. degree in chemistry, physics or materials science, and have significant experience with optical nanomaterials and/or time-resolved optical spectroscopy.

The work will be executed in the Physics and Chemistry of Nanostructures Group at Ghent University, Belgium. The postdoctoral researcher will be offered a one-year scholarship, renewable up to a maximum duration of three years. The scholarship is subject to a mobility rule: researchers must not have resided or carried out their main activity (work, studies, etc.) in Belgium for more than 12 months in the 3 years immediately before the recruitment date. In your application, please state how you fulfill this requirement.

To apply, please send your c.v., motivation letter and contact information for 2 references to iwan.moreels [at] ugent[.]be , using the subject line "application PHOCONA postdoc 3". The deadline for application is 12/04/2018.
