A natural way to address the scalability of quantum devices is to design and realise arrays of individual quantum objects with nearest-neighbor interaction. In large-scale semiconductor quantum processors, a quantum bit is encoded in the spin of an isolated electron, trapped in an array of quantum dots (QDs) [1]. Over the years, we have studied […] >>

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 […] >>

In recent years, the infrared imaging market has trended towards pixel size reduction. Interpixel crosstalk is a major limitation of small pitch devices, as it reduces the image resolution via the degradation of the modulation transfer function. The aim of this thesis is to study and fabricate pixel-level microoptics capable of reducing the crosstalk. The […] >>

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 […] >>

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 […] >>
