Reference : UPR2940-ELOBER-140
Number of position : 1
Workplace : GRENOBLE
Date of publication : 01 October 2025
Type of Contract : Researcher in FTC
Contract Period : 24 months
Expected date of employment : 1 January 2026
Proportion of work : Full Time
Remuneration : Between 2991,58 € and 3417,33 € gross salary according to experience.
Desired level of education : Doctorate
Experience required : 1 to 4 years
Section(s) CN : 03 - Condensed matter: electronic properties and structures
Missions
As a post-doctoral fellow, you will be responsible for the design and microfabrication of the laboratory-on-a-chip for measuring nanothermal test devices, as mastered by CNRS. These chips, either manufactured at NEEL or at LETI, are intended for use in measuring the thermal conductivity of nanometrically structured semiconductor materials.
Activities
The technological development of ultra-low temperature thermometers is at the heart of the lab-on-a-chip. These thermometers will be manufactured in-house in our Nanofab clean room, then tested by the TPS team in the experimental laboratory. You will be responsible for the technological development of these devices dedicated to electrothermal measurements. You will be responsible for manufacturing them in our cleanroom, developing the most suitable manufacturing processes, and then for characterizing and measuring them down to very low temperatures (50 mK).
Skills
- Strong experience in electrical and thermal measurement set-up;
- microelectronic technologies (lithography, etching, materials deposition etc.);
- manipulations and measurement in temperature regulated environment;
- strong expertise in cryogeny especially with dilution refrigerator.
PhD in physics (low-noise electrical measurements, nanoscale thermal measurements, microelectronics techniques, nanofabrication), you have several years' experience in experimental development and measurement, as well as in micro and nanofabrication; experience in low-temperature cryogenics (dilution refrigerator) is essential. Curious and open-minded, you are a hands-on person, at ease with experimental physics, you have knowledge of materials, lithography (optical and electronic) and you like disruptive nanotechnologies. Last but not least, you are fluent in English, rigorous and motivated by risk-taking.
Work Context
The 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 organisation.
The core mandate is to identify, carry out ou 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 recognised 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.
The postdoc researcher will be integrated in the "Thermodynamics and biophysics of small systems" team (16 members, including permanent and non-permanent staff) of the Condensed Matter – Low Temperatures (MCBT) department.
You will work at the Institut NEEL-CNRS 25 avenue des Martyrs on an innovative project selected and financially supported by the CRYONEXT project; a collaborative project between fundamental physics lab and industrial partners. Potential application will result from the research pursued here. Publications and/or patents will be at the core of the valorization of the results of the project with the different partners.
The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
