WebMar 19, 2024 · Rare earth nickel-based perovskite oxides (RENiO3) have been widely studied over recent decades because of their unique properties. In the synthesis of RENiO3 thin films, a lattice mismatch frequently exists between the substrates and the thin films, which may affect the optical properties of RENiO3. In this paper, the first-principles calculations …
WebFeb 4, 2024 · The nanocomposite thin films are improved and have high absorbance ranging from 92.5 % to 97.5 %, thereby, the decline in the energy gap and the increased surface roughness of the nanocomposite thin films led to increasing the absorption after adding CNT and CN to the polystyrene (PS) matrix.
