IJL employs 170 researchers and academics, 90 research support staff, 150 doctoral students and 25 post-docs.IJL collaborates with more than 150 industrial partners and academic collaborations with around thirty countries.
About Functional Thin Films for Energy applications group
The group studies the optical and electrical properties of thin films, nanostructures and devices obtained by the dry method (physical vapor deposition processes), mainly by IR / Visible spectroscopy and electrical measurements. These physical characterizations are completed by morphological and structural information obtained by electron microscopy (TEM, SEM) and X-ray diffraction (XRD).
Its research activity takes advantage of the possibility of creating thin coatings of complex compounds (such as oxides, nitrides, stable or metastable perovskites) or nanostructured films (transition metal nanoparticles in, or interfaced with, oxides) allowing to obtain original functional properties for three types of applications: thermochromism, optoelectronics and energy conversion.
With a long experience in vacuum deposition techniques, the group elaborates ceramic thin films and nano-structured layers by physical vapor deposition (PVD) methods.
The group has seven processing racks, three of which are connected to the D.A.U.M. Tube including
a semi-industrial machine.

Mission
The purpose of this internship is the use and development of tomography during the characterization of nano-objects by transmission electron microscopy. The nanomaterials observed will have various compositions and shapes and will have to be characterized at nanometric and atomic scales to understand the properties related to their use in different fields.
For the characterization of nano-objects, transmission electron microscopy is one of the most widely used methods because it can determine the shape, composition, and crystallographic structure at the nanometric scale. However, this technique generally only allows you to obtain a 2D image of a 3D object. By performing tomography in the microscope, it is possible to reconstruct the volumes and for example to locate variations in composition, pores, facets, etc. After acquisition of the data (images, diffraction images or elementary maps) at different angles, it will be a question of reconstructing in 3D the characterized particles to determine their shape and their crystallographic structure (by reconstructing the reciprocal network) and to locate with precision the elements present in the nano-object.
As part of the internship, the intern will perform the following missions:
• Bibliography
• Data collection by transmission electron microscopy
• Data processing to obtain 3D images or 3D maps
