Researchers from Korea's Institute for Basic Science (IBS) developed a new way to synthesize single-layer molybdenum disulphide (MoS2) using a gold catalyst. This new method allows MoS2 to be synthesized within a large area and any desired geometrical shape, and to be produced in the form of a semiconductor device.

The researched used the principle that a surface alloy is formed through the separation of molybdenum atoms and mixing them with gold when a chemical compound containing molybdenum is injected onto the surface of gold.
