Near‐Unity Polarization of Valley‐Dependent Second‐Harmonic Generation in Stacked TMDC Layers and Heterostructures at Room Temperature

With unique valley‐dependent optical and optoelectronic properties, 2D transition metal dichalcogenides (2D TMDCs) are promising materials for valleytronics. Second‐harmonic generation (SHG) in 2D TMDCs monolayers has shown valley‐dependent optical selection rules. However, SHG in monolayer TMDCs is...
