Nanomaterials and Advanced Heterostructures (NanoMAT)

The activity and expertise of the NanoMAT Team are focused on the chemical synthesis and crystal growth of low-dimensional materials (i.e. 2D and nanolamellar materials, ultra-thin films, nanowires, nanostructures, …) and their combination into innovative heterostructures. Our investigations aim at elucidating the nucleation and growth mechanisms of these objects, as well as determining and controling their morphological, structural, and physical properties at the nanoscale and at the different interfaces involved. These investigations that are essentially fundamental generally address applicative issues in the field of microelectronics, optoelectronics, and energy.

 

Research Lines

Our activity is divided in 5 research lines:

Nanolamellar materials

  • MAX phases, ultra-thin films, 2D materials
