Features in the FT at (1/2, 0). a Atomic-resolution topography of the x = 0.032 sample (same as Fig. 1b). The inset shows its FT. (0,1) and (1,0) are the Sr reciprocal lattice vectors. Scale bar: 7 nm. b Masked topography to remove the La1 features in a and its FT. c Linecuts along (1, 0) direction of the FT before and after masking La1. d, e dI/dV map at −4 and −84 meV, respectively. The blue and green dots denote the position of La1 and La2, respectively. dI/dV map at −84 meV shows glassy checkerboard-like modulation, clearly centered around the locations of La2. Scale bar: 3 nm. f Linecuts along (1,0) direction of the FTs shown in the insets of d and e
