Shape evolution of an etched pore with all edges terminated by NWs. ad Atomic resolution HAADF-STEM images showing the shape evolution of an initial NW-terminated parallelogram pore. e Polar plot of etching rates of NW-terminated ZZSe and ZZMo edge. ZZSe-NW (brown) etches more slowly than ZZMo-NW (black). f Simulated etching progress of the NW-terminated parallelogram pore shown in a. Scale bars are 2 nm
