Wireless power transmission technologies (WPT) are rapidly expanding, particularly for wireless charging of electrical systems (mobile phones, electric cars, etc.) but also for powering centimeter-scale wireless sensor nodes. The aim of the thesis is to study the performance and optimization of a new electrodynamic system concept recently proposed in our laboratory. The operation of this […] >>

Since 2018 and the announcement of the Spectre and Meltdow vulnerabilities, the hard-won performance gains of desktop and server processors over the past few decades have been called into question. These vulnerabilities effectively exploit the speculative and out of order execution found in all modern processors to gain in the number of instructions performed per […] >>

The focus today is on high luminance of the microdisplays to meet the requests for AR/VR application. The performance of current OLEDs, in terms of luminance and lifetime, especially for blue, have great difficulty in meeting these high luminance specdifications. Improvements in the efficiency and lifetime of the blue emitter are therefore mandatory. Fluorescent emissive […] >>

Two-dimensional (2D) materials are defined as crystalline solids consisting of a single layer of atoms, making their properties remarkable. Compared to their massive form, they can present outstanding semiconducting characteristics that can be exploited for many applications (CMOS, memories, photonics, photovoltaics, etc.). However, their integration into components via standard microelectronics processes remains a challenge and […] >>

The recent improvements of quantum bits (qubit) based on electron spins pave the way towards their massive integration into the possible quantum processor of the future quantum computer. The individual biasing, manipulation and reading of particular qubits of the matrix is a key point that forges strong links between physicists and electronics engineers. More specifically, […] >>
