WebJun 1, 2024 · In this sense, the compositional features were sufficient to distinguish different perovskites. Although our work demonstrates the great success of DFT-free descriptors using SR to accelerate the discovery of perovskite catalysts, there are several key challenges in extending SR to other catalyst systems. 4.2.1. Limited compositional flexibility WebThe aim of this course is to give a thorough introduction to Density Functional Theory (DFT). DFT is today the most widely used method to study interacting electrons, and its applicability ranges from atoms to solid systems, from nuclei to quantum fluids. In this course, we introduce the most important concepts underlying DFT, its foundation ...
