Supercell Band Calculations and Correlation for High-𝑇𝐶 Copper Oxide Superconductors [PDF]
First principle band calculations based on local versions of density functional theory (DFT), together with results from nearly free-electron models, can describe many typical but unusual properties of the high-𝑇𝐶 copper oxides.

DFT Calculation of Carbon-Doped TiO2 Nanocomposites
Titanium dioxide (TiO2) has been proven to be an excellent material for mitigating the continuous impact of elevated carbon dioxide concentrations. Carbon doping has emerged as a promising strategy to enhance the CO2 reduction performance of TiO2. In this study, we investigated the effects of carbon doping on TiO2 using density functional theory (DFT ...
