Fig. 1: Spontaneous curvature model for 2D vdW heterostructure.
From: Spontaneous curvature in two-dimensional van der Waals heterostructures
a The atomic model of Gr/BN bilayer before and after relaxation, with the out-of-plane fluctuation amplitude amplified by a factor of 3. b 1D schematic comparing the rigid model, surface reconstruction model and spontaneous curvature model. The green color represents the unstable stacking state. c Geometry schematic of a 2D interface with curvature.
