Room-in FFT, atomic structure and electronic structure analysis.
Room-in FFT of (a) image in bottom left panel (20 × 20 nm2 atomically resolved MEG image) and (b) Fig. 2d. Top right panel corresponds to zooming-in the FFT of inset in Fig. 1a. (c) The theoretically atomic structure of the 1D chain and 2D triangular structures. (d) dI/dV spectra of as-grown graphene and Bi adatom in hexagonal array.
