Photo‐ and Thermally‐Induced Huge Layer Decoupling in Twisted Bilayer WSe2

open access: yesAdvanced Materials, EarlyView.
A newly developed automated dark‐field tomography visualizes twist‐angle‐dependent structural relaxation and quantifies 3D structures in twisted bilayer WSe2. This approach reveals the evolution of local stacking configurations, thermally induced sub‐ångström interlayer decoupling, and light‐driven interlayer expansion on picosecond timescales ...
