Supertwisted WS2 spirals synthesized on step-edge non-Euclidean surfaces: Twist angle modulation and optical properties

Caption

Supertwisted WS2 spirals can be synthesized at the edges of nanoribbons, where larger step heights or contact areas of the nanoribbons lead to larger twist angles. The photoluminescence properties of the supertwisted structures reveal interlayer interaction decoupling and recoupling, while Raman spectroscopic analysis demonstrates lattice hardening dominated by interlayer van der Waals interactions.
