Missions

This project aims to develop the straintronics of 2D stacks by applying mechanical forces perpendicular to the plane in order to modulate their physical properties. Our objectives are: 1. to develop new 2D nanomaterials thanks to new bonding schemes between layers appearing at high pressure; 2. modulate the physical properties of 2D systems -- electronics including superconductivity, optics, plasmonics - by tuning the interaction between the 2D materials within the two- to n- layered stacks. Our studies will focus on homogeneous (including Moiré) as well as hybrid stacks of 2D materials. Mechanical forces will be applied using high pressure techniques up to tens of GPa range.

Activities

In this context, the postdoctoral fellow will design suspended membranes of graphene and other 2D materials on the one hand, and carry on their study under pressure on the other hand either by electronic transport measurements or by Raman spectroscopy under extreme conditions of pressure and temperature. Suspension of the 2D membranes is a challenge in terms of nanofabrication but is required to prevent invasive influence of the substrate. The research group combines complementary expertises in (i) the fabrication of nanostructures of complex geometries as platforms for straintronics testing; (ii) electronic transport measurements under pressure along with (iii) Raman imaging to determine the properties of these new materials.

Skills

The candidate must have a PhD and strong skills on condensed matter physics. The work will be essentially experimental and will include samples fabrication. Thus the candidate will already have some experience on nano-fabrication techniques, even stacks of 2D materials. In addition, an experimental skill in Raman spectroscopy and/or in electronic transport is required. Experience on high pressure/low temperature measurements will be an advantage.

Work Context

Néel Institute is one of the largest French laboratory for condensed matter physics. It is internationally reknowed and hosts 450 people. The postdoctoral fellow will have access to clean room facilities of Néel Institute, which provide in-house necessary equipment to perform sample preparation. The hosting groups have developed the experimental tools to address optical and electrical measurements under high pressure required for the project.
