Experimental and theoretical evidence for compression‐induced diamondization of few‐layer graphene is reported. Ab initio calculations predict that hydroxyl groups stabilize the sp 3 hybridization of the two topmost carbon layers, creating a single layer of hydroxylated diamond, or diamondol, when graphene layers are compressed in the presence of water. Electric force microscopy measurements reveal a compression‐induced charging inhibition of bilayer and multilayer graphene.
