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 fields of microelectronics, optoelectronics and energy, more particularly related to valence change memories, neuromorphic computing systems, self-powered UV photodetectors, nanostructured solar cells, piezoelectric nanogenerators and sensors, or even micro solid oxide fuel cells.
Research Lines
Our activity is divided in 4 research lines:
Nanolamellar & 2D Materials
MAX phases, ultra-thin films, 2D materials
MXenes: a new family of 2D electron systems obtained by MAX phase exfoliation.
The Team Nanomaterials & Advanced Heterostructures (NanoMAT) in LMGP is growing : it has hired at the beginning of 2022 a new CNRS Research Scientist, Hanna Pazniak, who is an expert in the field of MXenes.
