Growth of High Quality 2D Hexagonal Boron Nitride on a Liquid Metal Catalyst
Two-dimensional (2D) materials are crystals of one or a few atoms in thickness with high stability and physical properties governed by extreme quantum confinement. Due to its unique crystal structure, graphene exhibits a plethora of unconventional electronic phenomena. Hexagonal boron nitride (h-BN) shares the same crystal lattice but has different properties. For example, it is […] >>

Topological magnetic phases in quantum materials
We propose an experimental and fundamental research project which will explore different types of magnetic materials (EuPtSi, Gd2PdSi3, MnP, CrAs) with exotic magnetic states (skyrmion and helimagnet states). The goal is to use mainly thermoelectric effects under extreme conditions (low temperature, high magnetic field and high pressure), to characterize these exotic spin textures, understand the […] >>

Addressing retention and write bottlenecks for sub-10nm MRAM magnetic memory cells
Magnetic random access memories (MRAMs) are now on the market, in FPGAs or cache memory blocks. The concept of Perpendicular Shape Anisotropy MRAM (PSA) has been proposed to expand the MRAM market: the usual ultra-thin storage layer being replaced by a vertical magnetic pillar, allowing retention to be maintained at <10nm size and at high […] >>

Proximity effects between 2D materials and ferroelectrics
For their atomic thinness and exceptional electronic properties, 2D materials like graphene and transition metal dichalcogenides (TMD) are promising materials to build new compact and energy efficient electronic and spintronic devices. A key property of those materials is their two dimensional character which makes them highly sensitive to their environment. Thus, it offers the key […] >>

Development of a dilution refrigerator for space applications
In order to study the fundamental properties of Universe, it is necessary to measure very small intensity signals in a wide range of frequencies. To capture such a signal, the detectors matrices are generally cooled down to temperature of the order of 100 mK. In order to reach those temperature levels, a dilution refrigerator dedicated […] >>
