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.
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.

EMMC16 ( 16th European Mechanics of Materials Conference) aims at gathering researchers sharing a common interest in the field of mechanics of materials, yet working in a variety of application domains : material science, mechanical and civil engineering, but also biomechanics, geophysics, ...
Session 15 focus on Experimental nanomechanics :
Nano- and micromechanical testing coupled with advanced in situ techniques has attracted significant attention over the past decade because it permits (i) probing individual microstructure constituents and (ii) selectively activate mechanisms. Both is key to fundamentally understand plasticity and fracture of advanced multi-phase microstructures and small scale systems. The main objective of this thematic session is to gather specialists in the field of Nano- and Micromechanical testing to unravel mechanisms of plasticity and fracture at interfaces.
Characterization techniques envisioned comprise (but are not limited to) transmission electron microscopy (TEM), scanning electron microscopy (SEM) and synchrotron based techniques. The contributions should aim for understanding plasticity, fracture and fatigue at
- grain and phase boundaries
- amorphous / crystalline interfaces
- free surfaces
- multilayered systems
- super lattices.
This session is organized by Christoph Kirchlechner (MPIE, Düsseldorf, Germany) and Frédéric Mompiou (CEMES, Toulouse, France).
Abstract submission deadline: September 30, 2017.

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).
Applications should be made directly to University of Oxford, details here.
Informal enquiries are encouraged and should be addressed to Professor Alexander Korsunsky (firstname.lastname@example.org).
To apply formally for this studentship, candidates should send the following documents to email@example.com:
- 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.
The last decade has seen a tremendous evolution of X-ray imaging and microscopy. This has been driven by the rapid development of third and fourth generation X-ray facilities and X-ray optics capable of producing coherent beams routinely below 100 nm in size. The high penetrating power, extreme sensitivity of X-rays to strain and defects and the tunability of these new sources to access X-ray fluorescence of much of the periodic table has enabled in situ or operando studies of nano-scale properties materials. It is worth also emphasizing that small X-ray beams may also be used to induce an electrical current or light emission in the nano-object enabling enhanced scanning probe and photo excitation studies.
Beyond a discussion of the methods which have been developed, and are still an object of active research (coherent diffraction imaging in forward or Bragg conditions, nano X-ray fluorescence imaging, micro-Laue diffraction …), this symposium aims to disseminate knowledge of these new tools to a broader community of materials scientists.

This symposium is intended as an international forum for the presentation and discussion of the latest scientific developments regarding the physics and mechanics of fracture. Rather than addressing specific engineering problems and approaches, this symposium will cover fracture of brittle and semi-brittle materials at a fundamental level, with a focus on crack nucleation and crack-microstructure interactions. We aim at bringing together specialists from the fields of solid state physics, materials science, continuum mechanics, statistical physics and mathematics to cover theory, multi-scale modeling and experiments related to
• Initiation of fracture and crack nucleation
• Grain boundary fracture and interface cracks
• Crack – obstacle interactions
• Interplay of fracture and plasticity
• Fracture of nanostructures and disordered materials
• Fracture of composites
• Statistical aspects of fracture
• Micromechanical and local approaches to fracture
A special joint session on advanced micro- and nanomechanical fracture testing methods is envisaged with the planned EPS mini-colloquium »Mechanical properties at small scales« organized by Gerhard Dehm, Olivier Thomas and Laurent Pizzagalli.
The conference will take place at the Technische Universität Berlin.
Conference fee :
Students: 100/130 €
Regular Participant: 220/250 €

Deadline for abstract submission : 01.12.2017
