Institut NÉEL is a CNRS unit (UPR 2940) under agreement with the University Grenoble Alpes. The laboratory is related to the CNRS Physique. It is located in Grenoble, in the heart of a unique scientific, industrial and cultural environment. It is one of the largest French national research institutes for fundamental research in condensed matter physics enriched by interdisciplinary activities at the interfaces with chemistry, engineering and biology. It consists of 450 employees, including 175 researchers.
CNRS is a public, scientific and technological organization.
The core mandate is to identify, to carry out or to have carried out, either alone or with partners, all research that advances science or contributes to the country's economic, social, and cultural progress. Internationally recognized for the excellence of its scientific research, the CNRS is a reference in the world of research and development, as well as for the general public.

Today, an important research effort at the Néel Institute consists in advancing the understanding and development of quantum devices based on superconducting-semiconducting structures. They are key building blocks for next-generation quantum devices and low-temperature electronics. Among the teams involved in this research, the Nanophysique et Semiconducteurs team at the Néel Institute develops epitaxial planar interfaces that combine superconductors and semiconductors in the framework of the PEPR Techno Qauntique project QUANTIN. The outcomes could contribute to breakthroughs in quantum technologies and materials science.

The hosting team at Institut Néel is NPSC - Nanophysique et Semiconducteurs
Nanophysics and Semiconductors, which forms part of the PLUM department
