Within the Cluster of Excellence 3D Matter Made to Order (3DMM2O), which is supported by the DFG (German Research Foundation) as part of the Excellence Strategy, there is one open doctoral position.

The Nanoarchitected Metamaterials Laboratory of Dr. Jens Bauer (Institute of Nanotechnology, INT, at the Karlsruhe Institute of Technology, KIT) is seeking a doctoral researcher in the field of mechanical engineering for the development and mechanical characterization of Nanostructured 3D-Printed Metamaterials.

Job description:

Traditionally, material development has focused on the chemistry and microstructure of solids. Metamaterials go beyond these approaches and are composed of spatially structured building blocks (e.g., lattice architectures). Decoupled from the behavior of the base material used, spatial architectures enable a range of mechanical properties that would be impossible in the classical sense. Nanostructured metamaterials take this concept a step further. By miniaturizing their architectures through high-resolution 3D printing, they can exploit extreme material size effects. Thus, the architecture becomes a method for manipulating its own base material, with enormous potential for the development of future multifunctional high-performance materials, such as high-strength, ultra-lightweight nanolattices.

 

As a scientist, you will develop novel nanostructured ceramic metamaterials with the goal of utilizing material size effects in strength, plasticity, etc., through nanoscale three-dimensional architectures, which have so far only been demonstrated in individual nanofibers and nanoparticles. The targeted interplay of material and structural mechanics aims to achieve defect-insensitive, ductile deformation behavior with high-strength, inherently brittle ceramics. The experimental tasks include the nanofabrication of metamaterial samples, where various material morphologies are achieved through precise process control, and the characterization of their deformation behavior using scanning electron microscopy and nanoCT. Finite element simulations will also be essential for analyzing the response behavior, enabling a deeper understanding of localized mechanical effects and supporting the architectural design.

 

Our laboratory is a young and dynamic team with a flat hierarchy. Within 3DMM2O and the INT, we access a vast inventory of state-of-the art instrumentation and are part of a highly visible multidisciplinary network of experts. Further, we are in close exchange with collaborative partners at international top institutions, providing ample creative space, and opportunities to take divers responsibilities, and to expand your professional network.

 

Funding:

Scientific staff position (f/m/d) at 75% TV-L E13

Your profile:

  • A Master's degree in mechanical engineering or related subjects with above-average grades Passion for current research areas and drive to contribute to their development Excellent understanding of structural mechanics and materials science Fluent in written and spoken English Prior experience in micromechanical testing, 3D printing, or finite element analysis Competent in CAD software and skilled in data analysis using MATLAB

Application:

Applications should be handed in only through our Application Portal. Please indicate the position you are interested in so we can make sure to evaluate your application accordingly. The following documents and data are required for your application:

  • CV School and University (as applicable: Bsc, MSc, Doctorate) certificates
