Visible CMOS imagers can now be subjected to a complete battery of tests—for sensitivity, dynamics, dark current, noise, conversion factor, quantum yield, linearity, resolution, and remanence—on a new test bench developed by scientists at Leti. The new test bench, which also displays the generated images in real time, will round out the current electrical testing […] >>

Researchers from INAC and ESRF have teamed up with peers in Madrid to study the correlation between the chemical composition of a gallium nitride (GaN) nanowire and the temporal resolution of the wire’s optical response. To do so, they used new synchrotron instrumentation for fluorescence, diffraction, and photoluminescence. The new equipment offers spatial resolution of […] >>

Leti has developed an electromagnetic-wave propagation model to help improve the performance of BANs (Body Area Networks). The human body blocks electromagnetic waves and can have a considerable impact on wave behavior. The research involved taking several series of measurements at around 2.45 GHz. The experimental data were used to create a model that takes […] >>

Researchers from INAC, Institut Néel, and SIMAP recently figured out a way to observe the proximity effect in graphene—a phenomenon that occurs when a normally non-superconducting material is placed in contact with a superconducting material—under optimal conditions. To do so, they created a system in which the graphene remains totally free from atomic defects. Their […] >>

Prostate biopsies, which are performed if a cancerous tumor is suspected, could become more accurate and reliable thanks to a new fluorescence imaging technique. Leti researchers partnered with academic scientists and an SME to develop a new fluorescent marker coupled with a combined optical-ultrasound probe. The system renders any tumors visible for priority sampling during […] >>
