(A) A schematic illustration of the 2D ncp sphere arrays with new crystal lattices formed by stretching the PDMS film along one direction while maintaining the length in the orthogonal direction; SEM images of 2D ncp arrays on PVA-coated substrates with (B) square lattice, (C) parallel single sphere-wires; and (D) ordered array of parallel lines of the 2D ncp array. Insets in the right display the corresponding FFT images. A high magnified view of (D) is shown in the left inset (the scale bar is 2 μm). (Reprinted with permission from Reference [204].
