PhD position in piezoelectric ceramics design and characterization

DTU Energy

Do you want to contribute to a new way of designing and fabricating materials?

Many ceramic materials are highly anisotropic, such that their properties are much higher in some grain directions. However, we are yet not utilizing this to the full potential in combination with the shape control 3D printing now allows for. With a Villum Young Investigator grant funded by VILLUM FONDEN, we will try to understand how to simultaneously optimize both shape and grain orientation of ceramics, with piezoelectric ceramics for energy harvesting as the test case.

We now have an opening for a PhD-student for modelling and characterization of piezoelectric ceramics. The objective of this project is to investigate the optimum configuration of shape and microstructure of piezoelectric ceramics for energy harvesting. Your tasks will be a combination of design of shape and microstructure via considerations of anisotropy of the piezoelectric response and finite element modelling, and then a thorough piezoelectric and dielectric characterization of fabricated ceramics to validate the design. Another PhD project running in parallel focusses on developing the fabrication routes of the ceramics via 3D printing, but some fabrication might be required also in this project. You will be a part of a research team of 3-5 people working on similar methods and technologies (additive manufacturing and microstructure design, fabrication and characterization), within a larger environment at DTU Energy and DTU working with piezoelectric and electrostrictive materials.

You must have:  

  • A two-year master's degree (120 ECTS points) in Materials Science, Physics, Mechanical Engineering, or similar, or a similar degree with an academic level equivalent to a two-year master's degree.
  • Good communication skills in English, both written and spoken.
  • The ability to work independently with a strong drive, to plan and carry out complicated tasks
  • Interest in contributing positively to a new research group with a collaborative and diverse culture
  • A creative mindset for solving problems and identify new directions and opportunities in your project.

We highly value (but do not require) experience within several of these areas:

  • Piezo-, ferro- and dielectric materials
  • Vibrational/mechanical energy harvesting
  • Shaping and sintering of functional ceramics
  • Microstructural, structural and functional characterization of materials, e.g. SEM, EBSD, AFM, PFM, x-ray diffraction, impedance analysis, dielectric spectroscopy.
  • Scientific computing and programming, e.g. with MATLAB
  • Finite element simulations, e.g. with COMSOL
