"Revolutionizing Material Science: Unleashing the Potential of Atomic Sheets"

Researchers have developed a new approach to engineer atomic structures by stacking two-dimensional arrays in spiral formations, enabling metamaterials to overcome technical limitations and unlock novel light-matter interactions. By controlling the twist angle between layers of tungsten disulfide (WS2), the researchers created 3D nonlinear optical materials with chiral responses and tunable nonlinear properties. This breakthrough could have significant implications for next-generation lasers, imaging, and quantum technologies.
