Recently, we have introduced a way to transform basic LEDs into versatile multifunctional devices. Our strategy is to replace the standard active medium by an artificial composite (i.e. a metamaterial) made of colloidal quantum dots coupled with a metallic nanostructured pattern. The hybridization makes it possible to control all aspects of the electroluminescence at the nanoscale (electrical injection, polarization, color) and to weave light-emitting surfaces of unprecedented complexity.

Beyond the potential of these devices for applications (we have engaged in collaborations with major industrial players), it turns out that the physics at play in such artificial composites is new and quite unlike anything found in the literature and textbooks on nanophotonics. However, our understanding of this new regime of interactions at the nanoscale is still very limited.

The goal of this postdoctoral fellowship is to elucidate this new physics. Using time-resolved fluorescence measurements and transient absorption spectroscopy, the successful candidate will probe the dynamic of the carriers, their thermalization, their lifetime, and the thermodynamics of the structures at the nanoscale. This is a rare opportunity to make pioneering contributions in a nascent field, with experimental results that will serve as the foundations of many developments for years to come.


The work will focus on fundamental studies on ultrafast dynamics within artificial optoelectronic devices. Performing numerical simulations and participating to the fabrication effort in our clean room will also be part of the job.

The applicant should be able to write up articles and present his/her work in international conferences and workshops.


We are looking for a highly motivated individual with a strong experimental background in ultrafast optical techniques. A PhD training involving transient absorption spectroscopy would be welcome. At the very least, applicants should be proficient in manipulating and aligning femtosecond optical parametric amplifiers, as well as performing basic TCSPC measurements. At the same time, they should be open to collaborate with (and mentor) the students of the team and participate to the nanofabrication effort. A good level of English is also a requisite.

Work Context

The laboratory « Matériaux et Phénomènes Quantiques » (Quantum Materials and Phenomena) is a joint research unit (UMR) of University Paris Diderot and CNRS. It involves about 120 people in total with a permanent staff of 51.

The laboratory specializes in the study of frontier quantum materials and in the development of novel quantum devices. These activities rely on a large spectrum of theoretical and experimental expertise in material physics, transport and optics, and technological platforms of clean-room fabrication, spectroscopy and high-resolution electronic microscopy.

Constraints and risks

The successful candidate will work in a clean room. This platfom of 150m² has all the equipments needed to perform micro- nano- devices : we have installations for e-beam and optical lithography, wet etching and dry, metal and dielectric deposition.
