He will produce the samples using the technological means of elaboration available in the Leti clean room. […] >>

Quantum computing is nowadays a strong field of research at CEA-LETI and in numerous institutes and companies around the world. The Quantum Silicon Grenoble project, including CEA-LETI, CEA-IRIG and Néel Institut, aims to achieve a quantum computer based on quantum bits (qubits) in silicon. The operating conditions of qubits (cryogenic temperatures = 1K, high frequencies […] >>

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, […] >>

Over the past 20 years, wireless communication systems have continued to evolve and offer new services. Today, the success is such that the frequency bands below 10GHz are saturated and we are now turning to millimeter band frequencies. These frequencies offer the possibility to develop systems with higher data rates. However, they require beamforming to […] >>

Uncooled thermal infrared cameras, based on the micro-bolometer technology, are present in several domains of application: industrial monitoring, automotive, automation, defense … To follow those high volume markets, there is a strong competition to develop more performant focal plane arrays, with smaller pixel pitch and including innovative optical functionalities. In this miniaturization context and optics […] >>
