5 major scientific domains
IEMN scientific activity which covers a large domain going from the physics of materials and nanostructures to instrumentation can be divided into five major scientific domains
Fundamental studies (electronic structure, optical and mechanical properties, growth, photonics and plasmonics) of advanced materials (semiconductors, nanotubes, graphene, oxides, bio-molecular devices and systems…) and nanostructures are performed within three groups: Physics, Epiphy and Molecular Nanostructures&Devices. Interdisciplinarity (between physics, biology, chemistry and electronics), new concepts and fabrication of innovative devices (using nanotechnology facilities and nanocharacterization), development of green nanotechnologies for energy harvesting (PV, TEG), green materials and ultra low power electronics are the other fingerprints of the department.
The Micro and Nano-Systems department has developed a world renowned expertise in the development of micro and nano-systems. It is composed of a collection of faculty/staff/students (more than 50). It shares a set of world-class design, fabrication, and test facilities, including the 1,200 sq. ft. of cleanrooms, managed by the Institute. The members of the department conduct industry-relevant, interdisciplinary research on materials, processes, micro/nano-scale sensors/actuators and microfluidics that take advantage of progress made in integrated-circuit, bio, and polymer technologies. The major research themes of the department are: i) Materials and Processes for MEMS, ii) Actuators and Power MEMS, iii) Biological MEMS.
Technological breakthroughs are targeted, via the development of new materials and device structures, in order to overcome the current limits in micro- and opto- electronic components. Improving noise, power and frequency state-of-the-art boundaries is then the driving force of the different device studies that are carried out in microelectronics whatever the application is placed in the digital or analogue domain. Interactions between high frequency electrical signals and optical waves lead to develop innovative components in optoelectronics and THz domains from telecommunications up to sensors application fields.
With a long experience on circuit design, this department develops innovative systems for telecommunication and instrumentation applications. It covers a wide frequency range from base band up to millimeter wave frequencies (220 GHz) and has been a pioneer in impulse radio systems at 60 GHz. Main contributions concern high rate or/and high mobility communications and ultra low power communications: energy harvesting, storage and management, circuit design, heterogeneous integration, signal processing and cooperative communications for sensor networks and green radio. They rely on a good balance between theoretical works, experimental validations, demonstrations and realizations.
The Department of Acoustics at IEMN aims to develop fundamental knowledge on active materials and acoustic meta-materials, unusual properties of acoustic wave propagation and acoustical micro-systems in order to use this knowledge to design, fabricate and characterize electronic components and systems. Two interdisiplinary subjects illustrate these activities: networks of sensors for which innovative concepts and components providing specific functions for telecommunications, biology or instrumentation are studied; acoustic imaging in a broad sense with the development of new principles for imaging and non destructive evaluation.
