IEMN is a Joint Research Unit (Unité Mixte de Recherche) between Centre National de la recherche Scientifique (CNRS), Université des Sciences et Technologies de Lille (USTL), Université de Valenciennes et du Hainaut Cambrésis (UVHC) and Institut Supérieur d’Electronique et de Nanotechnologie (ISEN), but only staff from CNRS and USTL will be participating in this project. CNRS will be the beneficiary signing the Grant Agreement and the special clause 10 will be implemented to include USTL as a third party in the ROOTHz consortium.

iemnCNRS is a public organisation for scientific and technological research and is under the authority of the Ministry for Research ( It is also the largest fundamental research organisation in Europe. Its own laboratories as well as those it maintains jointly with universities, other research organizations, or industry are located throughout France, but also overseas with international joint laboratories located in several countries. Measured by the amount of human and material resources it commits to scientific research or by the great range of disciplines in which its scientists carry on their work, the CNRS is clearly the hub of research activity in France. It is also an important breeding ground for scientific and technological innovation.

8 scientific departments and 2 national institutes which cover all scientific fields : Physique Nucléaire et Corpusculaire (PNC, Sciences Physiques et Mathématiques (SPM, Sciences et Technologies de l'Information et de la Communication (STIC, Sciences Pour l'Ingénieur (SPI, Sciences Chimiques (SC, Sciences De l'Univers (SDU, Sciences De la Vie (SDV, Sciences de l'Homme et de la Société (SHS; Institut national de physique nucléaire et de physique des particules (IN2P3 et Institut National des Sciences de l'Univers (INSU The CNRS encourages cooperation between scientific fields and have several interdisciplinary programmes.

IEMN is partially supported by CNRS in the frame of the CNRS Institute of Information and Engineering Sciences and Technologies (INST2I). About 45 CNRS full time researchers are working at IEMN as well as engineers and technicians.

ustlUSTL is devoted to research and higher education. Its department devoted to Computer Science Electronics Electrotechnics and Automatics (IEEA) supports several laboratories including IEMN. About 110 assistant professors and professors from the university are working inside IEMN as partial time researchers.

USTL researchers benefit from various technological platforms which are constituted of high technology apparatus able to perform different kind of analyses or measurements: mass spectrometer, nuclear magnetic resonance (NMR), Transmission and Scanning Electron microscopes (TEM and SEM), Marine station-Sépia oceanographic boat, Optics, Lasers, Spectroscopes, Micro and Nanotechnology, Electrical characterization of components and devices, Scanning Tunnelling Microscope IEMN: Institut d’Electronique de Microélectronique et de Nanotecnologie (CNRS and USTL, France) (STM) and Atomic Force Microscopes (AFM), Telecommunication platform, fibre tower, Electron Paramagnetic Resonance (EPR), X-rays diffraction, virtual reality room, braking tribometre, optical metrology platform, etc.

iemnIEMN ( is one of the largest micro- and nanotechnology research centers belonging to the CNRS (Centre National de la Recherche Scientifique). IEMN has a staff of about 250 permanent researchers and teachers and about 150 PhDs and post-docs. The IEMN Technological Center supports the Institute's research teams but is also available to national and international academic and industrial laboratories.

The main tasks attributed to IEMN in the project are:

State of the art devices with nanometer dimensions for millimetre and submillimetre wave applications are fabricated at IEMN. T-shaped active ballistic devices with nanometre dimensions have also been investigated. On GaN, the PUISSSANCE team has developed a HEMT technology that has allowed demonstrating more than 10 W/mm at 10 GHz. THz antennas and UTC diodes have also been realized and characterized.

Resources to be committed: More than 27 engineers and technicians are full-time working in the 1600 m2 technological platform:

Staff members undertaking the work: C. Gaquiere, D. Théron and G. Ducournau will lead the work on this project, in which 2 CNRS and 2 USTL researchers and 4 engineers will be involved. Moreover, one PhD student (3 yrs) and one postdoc (2 yrs) will be appointed, dedicated, respectively, to i) microwave and THz characterization of emitters and detectors and ii) to the development of the technology for the fabrication of GaN based SSDs.

Prof. Christophe Gaquiere: Professor at the USTL and Dr. Didier Théron, CNRS Research Director, have a long experience on GaN technology and microwave characterization and are involved in the III-Vlab (common laboratory between Alcatel/Thales and IEMN), with focus on WBG semi-conductors. Dr. Guillaume Ducournau: Associate Professor at the USTL is involved in the research of optoelectronic THz generation by optical photomixing and the characterisation of THz detectors based on GaN/AlGaN structures.
