WebThe DFT+U method 5,6,7,8 is one of the common approaches to enabling charge localization. DFT+U adds a correction term (hence +U) to DFT calculations to help remove self-interaction errors. It requires little more computational time than standard DFT calculations, and is therefore one of the most popular methods for modeling polarons. WebFeb 14, 2024 · Density functional theory (DFT) suffers from self-interaction errors (SIE) that generally result in the underestimation of chemical reaction barrier heights.
