Abstract

We report the formation of a stable phase of gold single atoms driven by solid-state dewetting of nanoplates. Through atomically resolved approaches and combined spectroscopy, our study provides a still unexplored perspective on the solid-solid interface of gold crystals undergoing dewetting, unveiling its capability to stabilise exposed atomically dispersed phases as dense as ∼20 single atoms per 100 nm².
