Coherent consolidation of trillions of nucleations for mono-atom step-level flat surfaces

Abstract: Constructing a mono-atom step-level ultra-flat material surface is challenging, especially for thin films, because it is prohibitively difficult for trillions of clusters to coherently merge. Even though a rough metal surface, as well as the scattering of carriers at grain boundaries, limits electron transport and obscures their intrinsic properties, the importance of the flat surface has not been emphasised sufficiently. In this study, we describe in detail the initial growth of copper thin films required for… Show more

“…We prepared a lm with a thickness of 12 nm (equivalent to 56 atomic layers) to ensure both single crystallinity and high THz transmission, enabling reliable data analysis (Extended Data Fig. 1 for the single crystallinity of our Cu(111) lm) 14,15 . The Cu(111) lm shows resistance against oxidation.…”
