• The PMMH (Physics and Mechanics of Heterogeneous Media) is looking for a postdoc:

    Subject: "Multi-scale Modeling of Plasticity in Amorphous Solids."

    Description:

    The hired postdoc will be part of a multi-scale research project focused on the mechanical properties ofamorphous materials. Project efforts will focus on the characterization and modeling at mesoscopic and/or continuous scales, via numerical and theoretical approaches, depending of the background of the candidate. Using a coarse-grained approach, we will derive a constitutive law in the continuum mechanics framework, in accordance with the results harvested at atomic scales. A sustained dialogue with the other members of the group studying atomic level mechanics is therefore strongly desired to make the different approaches on different scales “feed” each other, the multi-scale aspect being a key point in this project.

    Desired skills and experience:

    Eligible candidates should hold a Ph.D degree in Solid State Physics, Mechanics, Materials Science or a closely related discipline, with expertise/experience in simulations of mechanical systems and good skills in programming (e.g. FORTRAN, C, Python etc.). An experience in molecular dynamics, in finite element method or in solid mechanics modeling is considered as a plus.

    Application:

    Application in English must be submitted electronically by sending an email with “Apply for ANR JCJC postdoc” as a subject to sylvain.patinet@espci.fr. The application must include the following:

    - Complete curriculum vita.

    - Complete list of publications.

    - Description of current research and a cover letter.

    - Full contact information (name, address, telephone & email) of three professional referees who may be contacted for references.

    The appointment of postdoctoral fellow will be for 18 months. Starting data is envisage in September 2018, but this is flexible.

  • -PhD: "Study of elementary deformation mechanisms of multi-component metallic alloys (high-entropy alloys) with a body centered cubic structure."

    This thesis is incorporated within the framework of fundamental research on High-Entropy Alloys (HEAs) with a body centered structure (BCC) – new alloys whose name emphasizes their inherent high mixing entropies.

    The proposed thesis is dedicated to the study of refractory HEAs with a BCC structure. The main objective of the work is to examine the evolution of mechanical properties of solid solutions Nbx(HfTaTiZr)100-x with x ranging between 20 and 100 (at.%). The proposed strategy would lead to identify the impact of elementary substitutions in the solid solutions on the mechanical behavior of the processes materials. The evolution of underlying deformation mechanisms will be at the center of the study and mainly performed by in-situ Transmission Electron Microscopy (TEM).

    Thesis supervision: Jean-Philippe Couzinié (Associate Professor [accredited research director], couzinie@icmpe.cnrs.fr) and Frederic Mompiou (CNRS scientist [accredited research director], frederic.mompiou@cemes.fr).

    LSPM research team (CNRS, UPR3407, Paris 13 University) will also be partner of the study under the supervision of Guy Dirras (Professor, dirras@lspm.cnrs.fr).

    Desired candidate profile: He or she should demonstrate a solid background in Materials Science with an excellent ranking/level in their Master’s degree.

    Beginning of the thesis/funding : 2018, 1st October; Deadline for application: 2018, 31 May.

    The thesis will be held at ICMPE in Thiais, near Paris , with long stays at CEMES in Toulouse.

  • The JRC is offering a post-doc and a trainee  position:

    -Post-Doc (24 months): "Exploratory Research Project Novel Micromechanical Testing Methods for the Characterization of Nuclear Materials/μMech."

    Description:

    The main activity concerns the development of novel micromechanical tests based on the in-situ deformation of metallic membranes produced by microfabrication techniques. The aim of the project is to develop a new methodology, including sample preparation, measurement procedures and data treatment and analysis, for mechanical testing of structural materials for nuclear applications.

    The candidate will be in charge of performing micromechanical testing ex-situ (using a nanoindentation set-up) and in-situ (inside a SEM). As well, he/she will be responsible for post-test examinations by electron microscopy, analysing the data and reporting.

    More information are available in the following document: « CA_Petten_2018.pdf »

    -Trainee (5 months): "Acquisition and analysis of nanoindentation results."

    Description:

    Nanoindentation is a mechanical testing technique that allows extracting local information of the mechanical properties of materials, such as hardness and elastic modulus. The JRC is involved in several international projects addressed to develop new methodologies for nanoindentation testing in quasi-static and dynamic modes, at room and at high temperatures. In this context, we are looking for a trainee to assist in the operation of nanoindentation equipment to set-up experiments, program and launch data acquisition matrices. The candidate will also be requested to perform post-processing of data, prepare data analysis reports and store the data in a materials database. A significant amount of work will be carried out in the laboratory followed by statistical analysis.The trainee could be an undergraduate/master student or a PhD student who would like to do a stay.

  • Subject: Characterization and Modeling of Dopant Diffusion Under Process-Induced Stress.

    Description: 

    The aim of the PhD is to reliably predict the impact of manufacturing process-induced stress on junction profile modification and subsequent electrical parameters shifts on sub-micrometric electronic active devices. The job will involve physical and electrical characterization of dedicated, previously designed simple test structures with a view to assessing the nature and magnitude of mechanical stress and dopant diffusion. A critical review and improvement (if necessary) of state-of-the-art stress-dependent dopant diffusion models will pave the way to an accurate Technology Computer Aided Design (TCAD) simulation of realistic (that is, manufactured) electronic devices.

    It will be performed in strong partnership with STMicroelectronics.

    Candidate profile:

    The ideal candidate has a Master Degree in Material Sciences (or equivalent), a solid background in semiconductor physics, good communication skills and is proficient in written and spoken English.

    PhD Advisor: Pr. Olivier Thomas; Email: olivier.thomas@im2np.fr; Laboratory: IM2NP (http://www.im2np.fr/); Industry: STMicroelectronics, Rousset–France (http://www.st.com); Funding: CIFRE (3 years); Location: Marseille (France), Rousset (France)

    Applications should be sent by email to Prof. Olivier THOMAS (olivier.thomas@im2np.fr) and/or Dr. Roberto SIMOLA (roberto.simola@st.com)

    Deadline: June 1st,2018; Starting year: 2018
