Second Harmonic Generation in Janus Transition Metal Chalcogenide Oxide Monolayers: A First-Principles Investigation
Due to the unique optical responses induced by vertical atomic asymmetry inside a monolayer, two-dimensional Janus structures have been conceived as promising building blocks for nanoscale optical devices.In this paper, second harmonic generation (SHG) tonic shower cap in Janus transition metal chalcogenide oxide monolayers is systematically invest
