About the Department

At DTU Energy we are starting a research project where we will use computer simulations to investigate the behavior of piezoelectric materials with the goal of improving their performance. Piezoelectric materials exhibit a coupling between electric and elastic phenomena. This means that applying an electric potential causes the material to deform, or vice versa: applying a mechanical force causes the material to generate an electric field and hence a current. As such, they are already used in a number of applications either as actuators or as power generators, especially for miniaturized devices, e.g Internet of Things (IoT) devices.

It is known that the performance of piezoelectric materials is determined by several features of their microstructure, e.g. size and shape of their crystal grains or presence of inclusions. However, in this project we investigate a yet unresolved question: how can we optimize the microstructure such that the best performance is achieved? To answer this question we will use phase-field modelling: an elegant mathematical formalism that can predict the behavior of the material at the micro- and nano-scale.

At DTU we developed a state-of-the-art phase-field simulation framework MagTense which can be used to model magnetic or electric effects at the micro-scale, as these are substantially analogous from a mathematical point of view. However, the framework is currently not able to handle the coupling with mechanical effects, which is required to describe piezoelectric phenomena. As part of your project, you will therefore develop the mathematical model to include this class of interesting physical effects in the existing modeling framework. Subsequently, you will use it to explore the relation between microstructure and performance of piezoelectric materials and devise ways to micro-engineer the microstructure to enhance the performance.

In the course of this project, you will become expert in different exciting physical phenomena that are relevant to green-energy technologies. Moreover, you will master a mathematical modelling technique, i.e. phase-field models, that has numerous applications in various scientific and technological areas. The project also involves a collaboration with the Polytechnic University of Milan, which you will visit for a few months as part of your PhD. There, you will have the opportunity to expand your knowledge by collaborating with world-leading experts in nano-scale modelling.
