Introduction       ↑↑↑

To envision the next generation of low cost devices based on doped colloidal quantum dots (CQD) active in the infrared (IR) spectral range, the FRONTAL project will quantify and analyze missing crucial parameters concerning the single nanostructure optical response and ultrafast dynamics of doped CQD in the near, mid and far infrared region (1-20 µm wavelengths).

Both ensemble and single self-doped HgSe, HgTe and one green alternative nanocrystals will be considered.

Based on a combination of cutting-edge techniques exploiting the electronic, optical, acoustical, thermal signatures of these nanostructures, and theoretical modeling in multiband k.p formalism, the partners will give a detailed description of the electronic structure (energies, dipoles), measure the times and identify the mechanisms ruling the relaxation of energy over time scale spanning the range 30 fs – 10 µs. The spectral, nanometric spatial, and ultrafast time resolutions seek to envision and enable in the future a more realistic design and optimization of doped CQD based infrared technologies that are presently emerging.

Objectives       ↑↑↑

FRONTAL aims at generating a detailed picture of the infrared nanocrystal optical response in the whole infrared spectral range, from the near infrared (wavelength ~1µm) to the far infrared (20 µm). To that end, using cutting-edge techniques, we will spectrally, spatially and temporally resolve the absorption of CQDs down to the nanometric scale and single nanocrystal level when possible, and down to the sub-100 fs time scale on ensembles.

1. We will describe the electronic structure free from hindering inhomogeneous effects in CQD ensemble like size dispersion, shape variation, doping inhomogeneity from CQD to CQD or inter-nanocrystal optical coupling.

2. We will unravel the intrinsic energy relaxation mechanisms from the measurement of the ultrafast dynamics of the confined electron(s). In particular we will investigate the strength of the electron-phonon interaction. To that end, several signatures of optical, acoustical, thermal, transport origins covering an as large as possible interval of wavelengths (1-20 µm), times (40 fs-10 µs) and spatial scales (few nm – few microns) will be exploited. Materials which synthesis and self-doping are already well controlled will be considered, namely intraband self-doped HgSe, interband HgTe and 2 green counterparts.

3. At the end the project will also list and tentatively envision the assets, or possibly the detrimental parameters, towards the use of CQD in future infrared optoelectronics devices with the precious technological and market knowledge of LYNRED.
