When bonding noble metals to 2-D materials, interfaces matter

The materials, based on two-dimensional transition metal dichalcogenides (TMDs) that include disulfides, diselenides and tellurides, have a variety of interesting properties that scientists would like to exploit, especially for next-generation electronics and catalysis.

The team deposited the noble metals gold and silver on the two-dimensional TMD substrates and studied how the metals formed and grew on the TMD surfaces. In every case but one, the metals formed zero-dimensional nanoparticles, as theory predicted. But in the case of silver deposited on ditellurides, the silver formed a single atom layer coating the entire substrate.
