Optimizing the electrocaloric effect by ab initio based simulations

Anna Grünebohm, University of Duisburg-Essen, Duisburg, Germany

Ferroic cooling is promising for novel sustainable cooling technologies [1,2]. However, to compete with conventional cooling technologies and Peltier elements, many challenges have to be met along the whole „Materials Chain“.

In this talk I discuss the benefits of ab initio based simulations for the fundamental understanding and optimization of the electrocaloric effect. In particular I will focus on different factors promoting inverse electrocaloric responses [3].
