2D layers of chalcogenide materials growth by van der Waals epitaxy for frugal electronics
Non-volatile magnetic memories (MRAMs), such as STT-MRAMs (Spin-torque Transfer MRAMs), appear to be extremely promising devices for reducing the energy consumption of memories. In this context, a very strong spin-orbit coupling at room temperature has been demonstrated in 2D heterostructures of Tellurium-based chalcogenide materials opening the way to new energy-efficient devices. On the other hand, […] >>

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 […] >>

Improvement of the contrast of photoplethysmographic measurements for the monitoring of physiological parameters
Photoplethysmography (PPG) is a non-invasive optical technique for detecting temporal variations in blood volume in tissues. PPG is used to monitor physiological parameters such as heart rate, pulse oximetry and blood pressure. PPG is a widely used method in physiological measurement systems, whether for consumer connected objects (smart watches, smartphones) or medical systems (oximeters). Even […] >>
