Transforming ultrathin Au films into 2D metallic nanostructures

Researchers have successfully developed nearly freestanding nanostructured two-dimensional (2D) gold monolayers, an advancement in nanomaterial engineering that has the potential to revolutionize fields like catalysis, electronics, and energy conversion. The process involved growing gold monolayers on an iridium substrate while embedding boron atoms at the interface between the gold and iridium. This innovative approach led to the creation of suspended monoatomic sheets of gold that exhibited a hexagonal structure with nanoscale triangular patterns.
