The first-principles calculations based on the density function theory (DFT) with the dispersion-corrected DFT-D2 method were performed to investigate the structure, energetics, electronic structure, defects properties and cation migration of KC8n(n = 1, 2 and 3) and KC12n(n = 1 ...

The general flow of the DFT spectrum estimation method can be summarized as follows: 1. Preprocessing: Before applying the DFT, it is often necessary to preprocess the signal to remove any unwanted components or artifacts. This may involve filtering, detrending, or windowing the signal. 2. Discr...
The DFT-D2 method proposed by Grimme is adopted to understand Van der Waals forces and Longrange interactions Optimized structures of gas molecules and initial XP (X=In, Ga) monolayers Taking the dissolved gases CH4, C2H4 and C2H2 in the transformer oil as target gases, the optimized ...
