The electronic and optical properties of phosphorene co-doped with vanadium and non-metallic atoms (B, C, N and O) are investigated by employing first-principles calculations based on density functional theory.
We propose lead-free potassium iodide perovskite solid solutions KBI3 with B-site mixing between Ge/Sn and Mg as potential candidates for photocatalysts based on systematic first-principles calculations.
