60 GHz with good spectral quality? Check!

A phase-locked loop (PLL) is the best way to generate the high frequencies—around 60 GHz—required for tomorrow’s 5G telecommunications and Wi-Fi. However, the higher the frequency, the lower the spectral quality—and transmission speeds. PhD candidate Clément Jany (who has since obtained...

“Valleytronics” make spintronics even better

An international team led by researchers from INAC recently demonstrated that, in SOI transistors, electronic spin alignment under an outside magnetic field is much easier when restricted to a single “valley.”

The valley index is a quantum number that shows...

Science Fair and EXPERIMENTA


MINATEC celebrates science

The 2015 MINATEC “Parvis des Sciences” Science Fair and fifth annual EXPERIMENTA Art, Science, and Technology Fair will be held on the MINATEC campus from October 8–10, with plenty of science-related activities for everyone, from hardcore science enthusiasts to the general public. MINATEC held its first “Parvis des Sciences” in 2007, and the event’s appeal has continued to grow, especially among school groups. The two-in-one event brought in more than 4,000 visitors in 2014.

This year attendees can choose from an impressive 30 activities—three times more than last year—, including nine interactive tours. New Science Fair partners...

“€96 million in eighteen months for CEA Grenoble’s startups”

Is this an exceptional era for startups based in Grenoble?
Sixteen startups from our research environment raised the record sum of €96 million from some 40 investors in just eighteen months. Aledia raised over €28 million, in addition to the €19 million raised by Crocus Technologies, €5.7 million by Exagan, €6.4 million by Isorg, €3.7 million by Apix Analytics, and €3 million by Primo 1D, as well as funds raised by ISKN, Enerbee, and Avalun. Almost all of these companies are operating out of MINATEC and more specifically the BHT.

Why this surge...
