The materials studied are the opposite of fractal structures, in the sense that their characterization at a given scale does not predict their structures at higher or lower scales. The most emblematic materials are composite materials, which can range from their simplest expression (nanoparticles in a matrix) to more complex configurations (nano-objects grouped in aggregates and dispersed in an anisotropic matrix).

Our field of research on these objects, whether 2D (surfaces and planar interfaces and grain boundaries) or 3D (nano-objects), covers areas ranging from formation mechanisms (nucleation, epitaxy, wetting, elasticity, diffusion and alloying effects, kinetics, role of ligands, a gaseous environment or a matrix…) to physical properties […] - [NeO-ENG](https://www.cemes.fr/neo-eng/): NeO Nano-Optics and Nanomaterials for Optics The NeO group “Nano-Optics and Nanomaterials for Optics” is interested in the interaction of light with structured matter at the mesoscopic or nanometric scale: – Studying the influence of size, shape, structuring and coupling of nano-objects on their linear and non-linear optical properties, as well as on their electronic and vibrational dynamics. – Use of these effects to shape the near-field to far-field optical response of individual nano-objects or an ensemble of nano-objects. – Design and fabrication of two- or three-dimensional architectures of nano-objects and microstructured materials for applications in fields as varied as […] - [PPM-ENG](https://www.cemes.fr/ppm-eng/): PPM Physics of Plasticity and Metallurgy The “Physics of Plasticity and Metallurgy” (PPM) group of CEMES aims at understanding the mechanical properties of mainly metallic materials.

These properties are tuned for applications in MOS, photonics, magnonics, memories or sensors. In the MEM group (Materials and Devices for Electronics and Magnetism), we study the link between the atomic structure and the electronic, optical and magnetic properties of these nanomaterial assemblies, in order to understand the physical processes governing these properties. The group relies on expertise in elaboration, structural and chemical characterisation down to the […] - [I3EM-ENG](https://www.cemes.fr/i3em-eng/): I3EM Interferometry, In situ and Instrumentation for Electron Microscopy The I3EM group, created at the beginning of 2016 during the reorganisation of the laboratory, stems from the desire to create a group focused on methodological and instrumental developments in transmission electron microscopy (TEM) and their use for advanced studies of the properties of nanosystems. The complementarity and diversity of the expertise of the members of I3EM allows original methodological developments in TEM to be carried out in order to solve material problems with optimal sensitivity and spatial or temporal resolution.

Our goal is to realise, in a single molecule or as few atoms as possible, a complex function such as long-distance information transfer (electronic, optical, magnetic) and a classical or quantum Boolean logic function, mechanical motion and classical <-> quantum transduction. In order to function, the molecule is integrated into a multi-scale architecture and, ultimately, coplanar with its nano-interconnections.

Spread over more than 700 m², including more than 400 m² in a clean room, our experimental tools pave the way for the atom-by-atom production of electronic circuits, the chemical synthesis of molecule-circuits or molecule-machines, as well as their electronic or mechanical interconnection, with picometric precision, by means of multiscale nanofabrication techniques. In addition, the ATP platform also brings together nanofabrication processes for the growth of thin metallic […] - [SCIENTIFIC HIGHLIGHTS](https://www.cemes.fr/scientific-highlights/): SCIENTIFIC HIGHLIGHTS Jan 03 , 2023 webevous Post Comment Couplage contrôlé d’émetteurs quantiques à des nano-antennes diélectriques à haut indice 3 janvier 2023 Couplage contrôlé d’émetteurs quantiques à des nano-antennes diélectriques à haut indice 3 janvier 2023… Lire la suite Nov 22 , 2022 webevous Post Comment Transport excitonique asymétrique dans une hétérostructure latérale MoSe2-WSe2 mis en évidence par spectroscopie optique exaltée par effet de pointe 28 novembre 2022 Transport excitonique asymétrique dans une hétérostructure latérale MoSe2-WSe2 mis en évidence par spectroscopie optique… Lire la suite Nov 09 , 2022 webevous Post Comment Les nanocristaux de Si dopés, des sondes […] - [CHEMISTRY & SOCIETY ASSOCIATION](https://www.cemes.fr/chemistry-society-association/): CHEMISTRY & SOCIETY ASSOCIATION CHIMIE ET SOCIÉTÉ OCCITANIE (CSOc) Since 2021, Chimie et Société Occitanie has had its headquarters at CEMES, interacting with the laboratory’s community of chemists to welcome the public during events such as the Fête de la science. The association, created in 2009, is the regional branch of the Chemistry and Society Commission of the Fondation de la Maison de la Chimie. It works to explain the scientific data underlying the debates in society in the region of Occitania, to make them accessible, in particular through a motivating and attractive popularisation approach.

We propose throughout the year events and activities aiming at the exchange and the conviviality between the non-permanent students of the laboratory. However, if it is aimed in particular at non-permanents (including trainees), it is open to all members of CEMES. The association was created on March 5, 2021 in the context of the COVID19 crisis, thus making it possible to maintain the link between non-permanents through the pandemic.

Its main objective is to reduce greenhouse gas emissions (GHG) and the environmental impact of its activity while maintaining quality research. Several working groups have been set up to: 1) calculate the annual GHG balance sheet using the GHG 1 point 5 tool (https://apps.labos1point5.org/ges-1point5) and thus establish a quantified basis of emissions according to different items 2) take measures to reduce emissions from buildings and fluids, transport (missions and home/work daily journeys), daily life and research practices.

The construction of the Boule was initiated by Gaston Dupouy, and the building was inaugurated in 1959 by General de Gaulle. It was designed to house the 1.5-million-volt electron microscope that operated from 1960 to 1991. The original microscope was later dismantled, but the electron accelerator has been preserved and still stands under the vault of the sphere. The Boule is a rare building, a successful architectural challenge of a director who wanted to make this unique microscope for its time known beyond the […] - [Organization](https://www.cemes.fr/organization/): Organization See the complete organization chart (in French) - [About us](https://www.cemes.fr/about-us/): ABOUT US ABOUT US The Centre d’Élaboration de Matériaux et d’Etudes Structurales (CEMES) is a CNRS laboratory (UPR 8011) associated with the Paul Sabatier University of Toulouse and the Institut National des Sciences Appliquées (INSA).
