Researchers at INAC recently synthesized homogeneous three-atomic-layer MoSe2 on a large scale using molecular beam epitaxy. Like other transition metal dichalcogenides (TMDs), MoSe2 is a two-dimensional semiconductor that offers vast potential for applications in electronics, spintronics, and optoelectronics. Producing the material by exfoliation from bulk crystal using adhesive tape does not deliver consistent enough quality […] >>

Power components now have their own transistor. Researchers at Leti completed the first-ever 600 V/100 A normally-off MIS-HEMT (metal-insulator-semiconductor high-electron-mobility transistor) offering performance compatible with the requirements of power electronics. In addition, the transistor can operate at 200 °C and can be manufactured at a reasonable cost. A 3 micron–4 micron GaN layer was deposited […] >>

INAC recently made a significant advance toward using spin-orbit coupling in transistors as the result of research conducted in conjunction with CNRS Palaiseau and Jülich Research Center of Germany. As its name indicates, spin-orbit coupling “couples” an electron’s momentum and spin. A new type of MRAM (magnetoresistive RAM) memory potentially capable of pushing back current […] >>

Molecular-size electrical wires will soon be a reality. Researchers from the Institut Charles-Sadron (CNRS, Strasbourg) successfully coated polymer semiconductor P3BT, or poly(3-butylthiophene), fibers with insulating nanotubes by two-dimensional self-assembly of liquid esters using a heterogeneous germination process. Researchers at INAC used atomic-force microscopy and transition-voltage spectroscopy to characterize the electrical wire obtained. They demonstrated that […] >>

Researchers at INAC, Leti, and LTM recently developed a novel single-cell bacterial identification method that uses a SOI nanophotonic optical structure that concentrates light to produce a very intense electromagnetic field that can attract and trap a single bacterial cell. Fluctuations in the intensity of the light transmitted by the optical structure due to interactions […] >>
