Missions

This project concerns the development of graphene/boron nitride (BN) epitaxial hetero-structures, to study the electronic properties of a novel generation of electronic devices. The underlying physical concept is the waveguide-type electronic transport that was recently discovered [1] in epigraphene* nanostructures [2] showing room temperature quantized ballistic conductance up to tens of microns.
These exceptional properties reveal topologically protected edge state conductance and are related to the graphene ground state at the charge neutrality point. Epigraphene gives access, for the first time, to this singular state that has remained elusive so far.
We have recently demonstrated that large-scale BN/epigraphene/SiC heterostructures produced by metalorganic vapor phase epitaxy [3] are of high structural quality and present the clean BN/graphene interface required to preserve graphene pristine properties. Electronic devices will be built directly
from these heterostructures and measured.
This project combines the expertise of the hosting group, with 20 years of experience in developing graphene for electronics, and the nitride research team at CNRS/Metz, the 2D material microscopy experts at ONERA – Paris, and the graphene surface group at CNRS/ Institut Néel in Grenoble. The project is developed in strong collaboration with the Georgia Institute of Technology in Atlanta, with
which extended collaborative exchanges will be organized.

Activities

The successful candidate will actively participate in the fabrication of samples (BN deposits for the fabrication of SiC / EG / BN heterostructures, structural studies), the design and production of devices by lithography, measurements electronic transport at low temperature, analysis and interpretation of data.

Skills

Doctorate in physics or equivalent
- Experience in electronic transport measurements and lithography techniques
- Material science skills a plus
- Good communication skills in English (written and spoken).

Work Context

The host group has a long experience in the development of graphene for electronics. The work will be carried out within the nitride group of the IRL CNRS-GT laboratory in Metz (Georgia Tech Lorraine campus ¼ hour from the city center), in close collaboration with the epitaxial graphene team at Georgia Tech in Atlanta, specializing in physics and nanotechnology from fundamental to applications
