Figure 2

a) Low magnification STEM image of Au MPC superlattice. The fast Fourier transform (FFT) pattern is inserted in the top of the image and shows six (6) strong reflection points denoted by 1 and 12 weak reflection points denoted by 2 and 3. The strong and weak reflection suggests the superlattice is made from the three lattice domains oriented along distinct directions. The magnified portion of the lattices are presented in figure b (lattice 1), figure c (lattice 2) and figure d (lattice 3). The direction for the lattice vectors a1, a2 and a3 is inserted in each lattice. The average angle measured between lattice 1 and lattice 2 is (13 ± 1)° and lattice 1 and lattice 3 is (30 ± 1)°, inferring that lattice 2 is rotated from lattice 1 by an angle of (13 ± 1)° and lattice 3 is rotated by an angle of (30 ± 1)°. e) A magnified portion of STEM images in lattice 1 for the statistics of distance between two MPCs. Three different directions are marked by 1, 2 and 3 and the intensity profile for corresponding direction is presented in the right panel and labelled as 1, 2 and 3. The average distance is obtained from the average between 20 values, the average distance along direction 1 is 6.3 nm, and direction 2 is: 6.06 nm and along direction 3 is: 6.17 nm. The FFT is inset in all cases.
