  Description du sujet:

Materials science and technology are our passion.

With our cutting-edge research, Empa's around 1,100 employees make essential contributions to the well-being of society for a future worth living.

Empa is a research institution of the ETH Domain.

Our Laboratory for Mechanics of Materials and Nanostructures in Thun is offering two PhD position founded by the Swiss National Science Foundation (SNF) in the field deformation mechanism of hexagonal closed packed (hcp) metals and alloys.

The Project

The research project aim at investigating the effect of solute atoms in the deformation twinning mechanisms of hcp alloys through the development of novel in situ testing experiments combined with advanced characterization techniques for strains, stresses and dislocation analyses at the nanoscale.

This includes the development of high resolution electron backscatter diffraction (HR-EBSD + 3D HR-EBSD), high resolution transmission kikuchi diffraction (HR-TKD), as well as the precession electron diffraction (PED) in the transmission electron microscope (TEM) during nano-mechanical testing.

In parallel to single and polycrystalline materials investigations, synthesis of hcp alloys will be done by advanced combinatorial physical vapor deposition (PVD) techniques.

Offer:

Empa in Thun, near Bern, offers an ideal working environment with excellent infrastructure for personal and professional development and is situated in a beautiful area in the German-speaking part of Switzerland.

You will be enrolled in the "Materials Science" doctoral program at EPFL in Lausanne.

The starting date is as soon as possible or upon mutual agreement and the PhD project is planned for 4 years.

Empa is the research institute for materials science and technology of the ETH Domain and conducts cutting-edge research for the benefit of industry and the well-being of society. Within the Laboratory for Mechanics of Materials & Nanostructures we investigate mechanical materials properties from the nano to macro-scale using experimental, analytical, and computational techniques. Current cutting edge research within European projects and ETH competence centers focuses on micro

- mechanical properties of materials (instrumentation, scale effects related to microstructure and physical dimension. For this purpose, we (a) develop metallic model materials either via electrodeposition in combination with UV- and electron beam lithography, nanoporous membranes and via focused electron or ion beam processing and (b) push resolution frontiers of materials microanalysis instrumentation, for instance of glow discharge based surface depth profiling and tip enhanced micro

• Raman spectroscopy. We focus on solutions for Swiss SMEs to increase mechanical reliability, production efficiency, and lifespan of new materials and systems ranging from thin films, watch parts and solar cells to power plant components.

Intitulé du doctorat:

• PhD in Materials Science
  Pays d'obtention du doctorat:
• SuisseYou must hold a Master's or an equivalent Degree in Materials Science, Mechanical Engineering or similar. A high motivation to work at the leading edge of measurement science and to work in an international, multidisciplinary research team is essential. Knowledge of English (oral and written) is important and knowledge of German or French would be an advantage. Experience in nanomechanical testing techniques (nanoindentation, micropillar compression), electron microscopy based techniques (SEM, FIB and TEM), physical vapor deposition, as well as programming (e.g. Matlab, Python or C++) is desirable.
