Researchers worldwide have studied the physical properties of two-dimensional materials, with the most notable discovery being that of the properties of graphene.
Discovered in 2010 by Andre Geim and Konstantin Novoselov, graphene was found to be a two-dimensional compound consisting entirely of carbon. It was the first two-dimensional material ever discovered, and Andre and Konstantin received the Nobel Prize in Physics in 2010.
Graphene has had many new applications in recent years, but more is still being learned about it to this day. Most recently, light energy was introduced to 2d materials to test the reactions. These materials reacted with vibrations, a new discovery.
The full applications are not yet and may never be fully understood, but the studies behind it are constantly revealing new uses and properties.
