Abstract
The present disclosure relates generally to thin metal films having an ultra-flat surface and methods of their preparation. In particular, the ultra-flat thin metal films comprise FCC metals. Preferably, the thin metal films are attached to a substrate. Preferred substrates comprise chalcogenides and dichalcogenides. Beneficially, the thin metal films described herein can be prepared at ambient temperatures.
Claims7
A thin film composition comprising:
- a substrate and a metal, wherein the metal has a first side and a second side, wherein the first side is attached to the substrate forming an interface, wherein the interface is opposed to the second side, and wherein the second side is a continuous flat surface;
- wherein the continuous flat surface has a surface roughness of less than 200 pm as measured by scanning tunneling microscopy;
- wherein the substrate comprises MoS2, and
- wherein the metal comprises gold and has a thickness of at least about 7.0 nm.
