Scientific collaborations

Over the years, Leti has engaged in scientific collaborations with experts in its major fields of excellence.

Each collaboration has brought new insight, ideas and concepts to light, strengthening our research, competencies and results in a mutually beneficial association. The richness of these exchanges is reflected in our partners experience of Leti, which some have shared with us during the interviews below. 

Today, Leti is more than ever pursuing and enlarging its cooperative approach to research with its academic networks in France and abroad based on the scientific excellence of the partnership.

Stanford University

‘Leti Is the Best Choice’ for Visiting Researchers 

Stanford University Prof. Yoshio Nishi came to Grenoble to head the Chair of Excellence Project funded by the Grenoble Nanosciences Foundation, and to work on the OxRAM project with Leti and IMEP-LaHC. The four-year project focused on developing a new memory technology: oxide-based resistive memories, in particular HfO2-based. 

Among its achievements, the team studied the impact of alloying/doping HfO2 with other materials for improved RRAM performances. Using ab-initio calculations, they pointed out that incorporating aluminium in HfO2 results in better thermal stability of devices, due to shorter bond lengths associated with their higher atomic concentration. This has been confirmed by experiments. 

Prof. Nishi, a professor of electrical engineering, spent several months in Leti’s memory lab, and co-tutored a PhD student and a post-doc. The team also published eight papers.

His relationship with Leti began about 30 years ago, when he was director of R&D at Toshiba and he met Leti scientists at conferences.

“I have known Leti for a very long time,” he said. “The culture is very welcoming and there is a very strong work ethic. When I left the office at 7:30 p.m., oftentimes people were still working, which is very different than in the U.S. and Japan. But I also was impressed at how the French people spent their weekends focused on their families.”

He found that Leti’s openness and commitment to innovation provide an encouraging setting for serious researchers.

After lunch in the cafeteria, people gathered in a space for coffee, with a wonderful view of the snow-covered mountains,” Prof. Nishi recalled. “It was very nice to speak with Leti people in that setting and, in fact, some very interesting ideas came from those discussions. I tell my colleagues that if they have the chance to work in a foreign country, Leti in Grenoble is the best choice.”

Telecom Bretagne

From Basic Research to the IoT: ‘Really Good Work and First Application of the Theory’ 

Prof. Claude Berrou from the Graduate School Telecom Bretagne teamed up with Leti researchers on a PhD project that built on the school’s work in artificial neural networks. Their innovation, which enables power efficiency on a small silicon footprint suitable for Internet of Things applications, demonstrated that features of neural clique networks can provide quick, optimal power management in electronic devices.

Prof. Berrou, who previously developed a new family of quasi-optimal error-correction codes called turbo codes, said Leti’s expertise and its emphasis on applications make it a top institute for visiting researchers.

“I am deeply interested in applications for research,” he explained. “Previously in France, technology was not considered important for academic researchers. But this has changed now, and academics are increasingly looking at applied science and technological applications.” 
Leti shares this vision and opens its doors to scholars interested in putting basic research to work to improve people’s lives.  

I’m very pleased with the experience of this project at the scientific level. It was really good work and the first application of the theory,” Prof. Berrou said. “We had several publications, and thanks to these, we proved the importance and the success of our theories.”
