A Schematic surface area composition modify by out-of-plane octahedral tilt in top look at. The lean contributes to a “dimer-like” composition forming by two apical I atoms within the top of adjacent inorganic cages. b Atomic-resolution STM image in the exfoliated n = four RPP at Vbias = +two.3 V. https://crithitceramics.com/allies/
