FM-AFM images of clinochlore. a Crystal structure of clinochlore crystal, which is composed of negatively charged talc-like (T) and positively charged brucite-like (B) layers. The figure was drawn using VESTA42. b Topographic image of the clinochlore (001) surface. The triangle shows the characteristic shapes due to the partial dissolution of the B layer29. c Cross-sectional profile along the P–Q line indicated in b. d Atomic-resolution image of the clinochlore (001) surface showing that the B island has two regions (BI and BII) with different heights. In the blue square, the contrast was enhanced and smoothed by a Gaussian filter. e, f Magnified atomic-resolution images taken on the T region (e), and BI region (f), with the inset of an FFT-filtered image. All of the images were acquired with ∆f ~ + 300 Hz. Scale bars: 100 nm (b), 3 nm (d), and 0.5 nm (e, f)
