Until now, it was considered that the damaging effects of UVB rays on DNA were due to the excitation of the bases, which produces pyramidine dimers. However, an experiment completed under French National Research Agency project OPHID, in which INAC is participating, showed that irradiation of genomic DNA at 295 nm also caused oxidation damage, […] >>

structures in which giant magnetoresistance (GMR) has been observed. Rather than stacking ultra-thin magnetic and non-magnetic layers, the researchers deposited the layers on the same surface. For example, two magnetic materials can be separated by a non-magnetic spacer a few dozen nanometers thick. The GMR variations measured on a pairing of cobalt and iron were […] >>

Since 2014, several scientific articles have presented the silicon-28 isotope as a good material for spin qubits for quantum computing. However, researchers had yet to produce the material in a CMOS environment, which uses natural silicon containing 4.7% isotope 29—not as suitable for qubits. INAC and Leti recently made a first step forward with the […] >>

Transition metal dichalcogenide (TMD) monolayers are promising candidates for future generations of transistors and for superconducting spintronics. The materials offer the advantage of retaining their superconducting properties even in the presence of very strong magnetic fields. Researchers at INAC dug deeper to come up with a theory to explain the phenomenon. They discovered that TMD […] >>

In February Leti presented a functional prototype of an 11 mm x 7 mm CMOS image sensor whose unique feature is that it is curved. The innovation could lead to a spectacular reduction in the size and complexity of lenses. It also opens the door to a whole new breed of microelectronics where the flat […] >>
