Scientists create novel bandgap-tunable 2D nanosheets made from perovskite oxynitrides

Kumamoto, Japan (SPX) Mar 21, 2023 Two-dimensional monolayer nanosheets made from layered perovskite have many desirable properties. However, it has been difficult to create them with tunable bandgaps in the visible region without adding oxygen defects. Recently, researchers from Japan were able to successfully develop chemically stable nanosheets from perovskite oxynitrides which had controllable bandgaps. These nanosheets have
