Two-dimensional (2D) crystal growth over substrate features is fundamentally guided by the Gauss-Bonnet theorem, which mandates that rigid, planar crystals cannot conform to surfaces with nonzero Gaussian curvature. Here, we reveal how topographic curvature of lithographically designed substrate features govern the strain and growth dynamics of triangular WS<sub>2</sub> monolayer single crystals. Single crystals grow conformally without strain over deep trenches and other features with zero Gaus ...[more]
