nanoMIR is a world leader in III-Sb technology, i.e. the family of III-V compounds based on GaSb, InAs, AlSb, InSb, their alloys and their heterostructures. It aims at developing this technology and its applications.

The antimonides (III-Sbs) are III-V semiconductors with effective band gaps particularly well suited to the mid-infrared (mid-IR~2 – 12 µm), a wavelength range which exhibits transparence windows of the atmosphere as well as strong absorption lines from many gas species. The mid-IR is thus very well suited to develop a variety of applications with important societal impact such as gas analysis (pollution or process monitoring, physics of gases, of the atmosphere,…), medical applications (surgery, diagnosis,..), free-space communications, but also security- and defense-related applications (counter measures, detection of toxic or explosive species, night vision,…).

For the last ten years, nanoMIR has been mainly focusing on developing mid-IR optoelectronic devices (lasers, photodetectors, highly-coherent laser sources) for these applications. It has achieved a number of breakthroughs which can be traced back in the list of publications.

Another objective of the group is to perform more fundamental studies and to explore the full potential of the III-Sb technology. So, activities on the integration of the III-Sb devices with the Si technology, on all-semiconductor plasmonics or on gas sensors have recently appeared. On the other hand, new exploratory topics (Optical Parametric Oscillations, topological insulators, concentrated photovoltaics,…) are emerging.

You can find more about each of these topics in their dedicated pages.



nanoMIR competences span the whole field from semiconductor-nanostructure epitaxy to device and system-prototype implementation, via heterostructure characterizations, design, processing and investigations of devices. To reach our objectives, the group has a number of fabrication and characterization set-ups devoted to material and device studies. In particular, we run three molecular-beam epitaxy (MBE) systems, several FTIR spectrometers and clean room equipment for processing technologies  

nanoMIR is a research group of “Institut d’Electronique et des Systèmes”, a research laboratory of Université de Montpellier jointly operated by CNRS (UMR 5214). The research is carried on by 13 permanent scientists and, typically, 5 to 10 PhDs students or post-docs.

Four technical (J.M. Aniel, G. Boissier, A. Meguekam, G. Narcy) staff actively and efficiently support the research efforts.

nanoMIR is or has been supported by a number of institutions such as the European Union (FP6, FP7, H2020 programs), the French “Agence Nationale de la Recherche”, the French “Délégation Générale de l’Armement”, the Région Languedoc-Roussillon, ADEME, SaTT AxLR,….


nanoMIR has been awarded an EquipEx (project “EXTRA”) by the French program on “Investments for the Future” and it is a founder of the international CNRS laboratory ILNACS.
