In the framework of the “Laboratory of Excellence (LABEX) EMC3” project, the Group of Materials Physics (GPM) has been granted an Early Stage Researcher (ESR) position in advanced correlative microscopy. The project proposes to extend the actual domain of application of the Photonic Atom Probe (PAP), an instrument coupling the capabilities of Atom Probe Tomography (APT) and photoluminescence (PL) spectroscopy in an in-situ approach. This instrument has so far been applied to the study of a very restricted number of materials systems.
The main objectives of the projects are: (i) update the current instrumental setup, in order to make it more user-friendly and flexible with respect to the studied material system; (ii) explore a set of materials systems (semiconductors, insulators, rocks) in order to establish which of them may be the object of a PAP analysis, (iii) develop sample preparation methods adapted to the localization of regions with specific optical properties (single emitters, quantum dots) and to their insertion within an atom probe tip specimen. This would pave the way to the possibility of performing a correlative optical / chemical analysis of single light emitters, and even optically active point defects. As an outcome of these experimental exploits, we expect a deeper insight into the physics of nanoscale light emitters and point defects, into the physics of field ion emission, and, generally, a gain in the influence of the PAP within the materials science communities.


- Development of correlative microscopy methodologies (responsible, main task)
- Identification of regions containing defects by standard scanning electron microscopy, electron beam induced beam imaging, cathodoluminescence imaging and spectroscopy. (responsible, main task)
- Asssitance in the instrumental developement of the Photonic Atom Probe (PAP)
- Fabrication using the Focused Ion Beam (FIB) of samples analyzed by Tomographic Atomic Probe (SAT) and Transmission Electron Microscopy (TEM). (responsible, main task)
- Sample analysis by SAT coupled with micro-photoluminescence spectroscopy (μPL) (secondary task)
- Calculation of electronic states by dedicated digital tools (e.g software nextnano) (secondary task)
- Publication of the results on international newspapers following the writing of scientific articles.


- Experience (>= 3 years), during his PhD or post-doctorate, in two or more of these techniques: Atom Probe Tomography (APT), Transmission Electron Microscopy (TEM), Nano-fabrication by Focused Ion Beam (FIB) ), Spectroscopy and Cathodoluminescence (CL) imaging.
- In-depth knowledge of semiconductor physics, in particular applied to optoelectronic devices
- PhD in Physics, Materials Science or Engineering

For the adaptation to the position, GPM offers annual APT and TEM training.

Work Context

The GPM (Group of Physics of Materials, UMR CNRS 6634) is structured in 5 departments: Materials-Aging-Mechanics, Scientific Instrumentation, Nanosciences, Disordered-Polymer Systems and Nano-Health-Physics. It brings together 160 staff including 60 Teachers-Researchers, 30 ITAs and 70 PhD students / PostDoct / Trainees.
