Special Seminar: Finding the needle in the haystack—Materials discovery through high-throughput ab initio computing and data mining

Geoffroy Hautier, Assistant Professor, Université catholique de Louvain

Rm. 100 (Spanos Auditorium), Cummings Hall

New materials enable technological breakthroughs in many fields from energy to electronics. The discovery and development of novel materials with unique properties is a long and difficult process. In the last few decades, computational techniques based on solving the fundamental laws of quantum physics at the atomistic level, so-called ab initio techniques, have risen as a powerful way to compute materials properties. This approach has offered unprecedented insight into materials behavior but also a powerful tool to predict materials properties. When coupled with the exponential increase in computational power, this predictive power provides an opportunity for large-scale, high-throughput, computational searches for new materials. We can nowadays screen thousands of materials by their computed properties even before the experiments. This computational paradigm allows experimentalists to focus on the most promising candidates, and enable researchers to efficiently and rapidly explores new chemical spaces.


In this talk, I will present some of the challenges and opportunities in high-throughput computational materials discovery using examples in various fields from transparent conducting materials to batteries. I will especially highlight computational predictions which have been followed by experimental synthesis and characterization. In addition to allowing the ability to navigate through a large volume of materials data to identify promising compounds, high-throughput computing also offers unprecedented data mining opportunities to detect new relationships between chemistry, structures, and properties. This will be as well illustrated along the talk.

The impact of high-throughput computing is multiplied when the generated data is shared with free and easy access. I will finish my talk by presenting the Materials Project, a collaborative project which precisely targets such a data dissemination.
