  • Subject: Modélisation et caractérisation des effets de nano-compliance pour la croissance épitaxiale localisée de GaN sur substrats Si.

    Project:

    In order to decrease the dislocation density induced by the different crystalline structures between the nitride semiconductor layers and the Si substrates they are grown onto, one often uses localised epitaxy methods. However, these result in the formation of other defects arising between the adjacent nucleation centers.  We have developed an original localised epitaxy method by which the crystallites are deposited onto deformable nano-pilars, allowing these crystallites to join without creating any defect. The PhD work we propose aims at a better understanding, for a better control, of the mechanical and thermo-mechanical processes at pla  during this process of nano-pendeo compliant epitaxy. This will be dealt with using finite element models so as to predict the mechanical behaviour of these complex nano-structured systems and by using an ensemble of structural nano-characterization tools for assessing the defect and strain distribution in the materials. From the reduction of defects in the epitaxial layers, we expect to address some of the main issues for a number of important applications related to these nitride materials in the opto- and micro-electronic domains.

  • EMPA is looking for a post-doc in the field of: Mechanical properties of ceramic thin films.

    Your tasks:

    You will work on applied research projects funded by InnoSuisse as well as on basic science projects on the small scale mechanical behavior of materials. You will exploit small scale mechanical testing facilities to study deformation and fracture mechanisms of hard ceramic coatings and nanocrystalline ceramics under extreme conditions of temperature and strain rate. You will characterize the microstructure of the deformed and fractured materials using cutting edge analytical techniques such as scanning and transmission electron microscopy. It is intended that all research output from the projects be publishable in peer-reviewed scien-tific journals, and the candidate will be expected to take a lead in the writing process.

    Your profile:

    You must hold a PhD in Materials Science, Physics, Mechanical Engineering, or similar. A high level of motivation to work in close collaboration with industry, experimentalists and an international, multidisciplinary research team is essential. Experience in small scale mechanical testing and/or analytical techniques such as TEM, FIB, XRD, SEM etc. is desirable, as well as in hard coating materials.

    For further information about the position please contact Dr Thomas Edwards  thomas.edwards@empa.ch or Dr Johann Michler, johann.michler@empa.ch .
