1.         PhD position in piezoelectric ceramics design and characterization

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

3.         Two PhD scholarships to tackle challenges in organic photovoltaics for the green transition using ultrafast XFEL experiments and computational chemistry

 

Two 3-year PhD scholarships in Experimental Ultrafast X-methods and in Theoretical and Computational Chemistry are available at the Molecular Movies group at DTU Physics and the Theoretical, Computational and Femtochemistry at DTU Chemistry. Together, we investigate ultrafast dynamic changes of inter- and intra-molecular structures during chemical reactions. Our main tools are time-resolved X-ray scattering, theory, and computer simulations in combination with complementary tools such as optical and X-ray spectroscopies. Using these methods, we aim to understand the details of the interplay between electronic and structural degrees of freedom which determine the outcome of chemical reactions, and through this understanding contribute to the development of new, functional materials for photo-catalysis and solar energy harvesting.

In this project we will target organic molecular systems that form the key building blocks in a new type of photovoltaics that has the potential to significantly increase their quantum efficiency through unconventional processes such as singlet fission.

You will work as a team together with members of our groups and with international collaborators. The experiments address structural dynamics and electronic processes from nanoseconds down to the femtosecond time scales and will be carried out at large-scale X-ray Free Electron Laser (XFEL) facilities in California, Japan, and Europe. The computational chemistry will use quantum chemistry and non-adiabatic dynamics simulations. Both projects will utilize and further develop tools for analyzing time series of extremely large data sets. The goal is to create a computational-experimental framework for mapping – with ultrafast atomic scale resolution – clearly separated observables of the electronic and structural degrees of freedom; to provide insight that will pave the way for new approaches to tailor organic materials for photovoltaics.

The PhD projects will be carried out under the supervision of Professors Martin Meedom Nielsen at DTU Physics (XFEL experiments) and Klaus Braagaard Møller at DTU Chemistry (computational chemistry) and are starting as soon as possible.

Responsibilities and qualifications
In both PhD projects, you will be involved in experiments and computational methods. One PhD student will take the lead in carrying out XFEL experiments, preparing samples and developing new procedures to combine and analyse time resolved X-ray spectroscopy and X-ray scattering data in close connection with modelling. The other PhD student will be responsible for carrying out computer simulations of electronic-structural trajectories of light-induced charge and energy transfer processes in a series of organic molecules; and calculate the corresponding experimental signatures and benchmark against experimental findings.

For both positions, active dissemination of the obtained results, in scientific articles and through participation in international conferences, is an integral part of the project.

You will be working in an international and collaborative environment with highly ambitions people depending on you, so you should be hard working and strive towards scientific excellence.

You are motivated, independent, and interested in chemistry and physics.

For the experiment-oriented position, you must have a strong training in X-ray and/or fs-laser based techniques and some experience in developing software tools (in e.g. MATLAB or Python) for data analysis. Experience with beamtime experiments at international facilities and with photophysics or photochemistry would be an advantage.

For the computational chemistry-oriented position, you must have a strong theoretical and computational training including programming skills and the ability to carry out quantum chemical calculations on your own. Experience with non-adiabatic molecular dynamics (such as SHARC, Newton-X, or similar methods) and/or wave-packet dynamics (e.g., MCTDH) would be an advantage.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education.
