What’s Inside a Graphene Sandwich?

In a recent study, researchers synthesized 2D cuprous Iodide stabilized in a graphene sandwich—and the material does not exist in normal laboratory conditions. The new material was born using the large interlayer spacing of oxidized graphene multilayers that allows iodine and copper atoms to diffuse into the gap. The graphene layers create high pressure on the sandwiched material, stabilizing it.

Researchers have already expanded the synthesis method to produce other new 2D materials. For more information, visit: Toward Exotic Layered Materials: 2D Cuprous Iodide
