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

    The aim of the PhD is to reliably predict the impact of manufacturing process-induced stress on junction profile modification 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.

    Deadline : September 2017   
    Starting year : 2017   
    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).

  • Project:

    The studentship is part of a funded project on refractive optics for X-ray wavefront correction being jointly undertaken by the University of Oxford (A.M. Korsunsky) and Diamond Light Source (K. Sawhney and D. Laundy).

    Diamond Light Source (http://www.diamond.ac.uk) is the UK’s national synchrotron science facility. The facility provides intense beams of X-rays delivered along beamlines to diverse experiments. Specialised X-ray optical components are used to focus the X-rays into sub-micrometre focal spots to obtain high photon flux density and high spatial resolution at the sample. Currently the smallest X-ray spots achievable at Diamond are sub 100 nanometre. Achieving such small focused X-ray beams places great demands on the quality of the X-ray focusing optics. The Optics Group at Diamond are developing micro-fabricated refractive optical components to correct for the fabrication errors in X-ray focusing optical components with the potential to obtain X-ray focal spots sizes of less than 10 nanometre in size. This would be of great benefit to the cutting edge experiments performed at the synchrotron.

    The successful applicant will participate in the design and fabrication of this novel X-ray optics; evaluation of the optics, in particular performing sensitive measurements to characterise the new optics on B16, the Test Beamline.  At Oxford, the student will become a member of Prof. Korsunsky’s group (MBLEM).

    Application:

    Applications should be made directly to University of Oxford, details here.

    Informal enquiries are encouraged and should be addressed to Professor Alexander Korsunsky (alexander.korsunsky@eng.ox.ac.uk).

    To apply formally for this studentship, candidates should send the following documents to postgraduate.studies@eng.ox.ac.uk:

    • CV
    • Covering letter (explaining your suitability for the study, what you hope to achieve from the DPhil and your research experience to date)
    • Contact details for two academic or professional referees

    Start in October 2017.

    Application deadline: Friday 28th July, 2017, Interviews will be held in mid-August, 2017.

  • Subject: OkMC simulations of dislocation loop evolution in presence of dislocation lines in Fe/FeCr under irradiation.

    The objective of this PhD is to simulate the evolution of defects in structural materials (stainless steels) such as Fe/FeCr under neutron and ion irradiation in order to evaluate the number and types of defects that interact with dislocation lines, which can lead to hardening of the material. Simulations will be mainly performed with the recently developed (at CIEMAT) code Object kinetic Monte Carlo based on GPU programming. This work will be carried out in the framework of the European H2020 project M4F (Multiscale modeling for fusion and fission materials), that will start in September 2017.

    Required skills: Good background in C++ programming. Knowledge of CUDA programming will be highly appreciated. And a strong motivation!

    If you are interested, please contact Dr. Christophe Ortiz (christophe.ortiz@ciemat.es).
