The group is involved in the design of optoelectronics devices using nanocrystals as active materials. To do so, we grow a broad range of material, see figure below:

The team is fully furnished to perform nanocrystal growth and their characterization

The group has a special focus on narrow band gap material and for this topic we also developed new synthetic procedure. For example, we report the first highly concentrated synthesis of HgTe nanocrystals by swicthing from conventional mercury salts to liquid mercury as precursor. We thus obtained the most concentrated synthesis of HgTe nanpocrystal ever reported with concentration close to 100 g/L. This new synthetic route is promissing to achieve greener synthesis of HgTe with reduced exposure of work force to Hg precursor.

We have also been the first to report nanocrystals with THz absorption. A new synthetic procedure has enable the growth of nanocrystal with size above the Bohr radius, thus enabling absorption up to 100 µm. This work demonstrated the possibility to tune the absorption of HgTe nanocrystal all over the infrared from 1 to 100 µm.
