(a) High-resolution STM image of a regular and a defect-bound Au atom (box) deposited on CeO_2–x/Ru(0001) at 15 K (+2.5 V, 3.8 × 3.0 nm²). (b, c) Identical surface region on a √3-reconstructed CeO_2–x /Pt(111) film before and after exposure of 0.05 ML Au at 15 K (−3.0 V, 10.5 × 8.0 nm²). Adatoms and their binding sites on the pristine surface are marked by circles. (d) CeO_2–x/Ru(0001) after gold deposition at 15 K and after annealing to (e) 200 and (f) 400 K (2.5 V, 30 × 30 nm²).
