Figure 1: Local crystallographic analysis of atomically resolved STM image.
From: Chemically induced Jahn–Teller ordering on manganite surfaces
(a) Occupied-state STM image of a 20 × 20 nm surface region of in-situ-grown LCMO film scanned with a bias voltage of −1.75 V (scale bar, 4 nm). (b) Map of oxygen vacancies found using the Fourier filtering procedure. (c) The adatom lattice obtained using the thresholding procedure. (d) Computed locations of adatoms and vacancies overlaid with the topographic image. Calculated locations of adatoms and vacancies are labelled with cross marks and open symbols, respectively. The inset is an expanded map for a better view.
