Deskripsi
Understanding the atomic arrangement and binding nature of 2D materials with substrates is crucial to understand their properties and utilize their functions. Here, authors report that at high temperature graphene and α-Al2O3 substrate form a C-O-Al bond, having strong interactions, while interfacial structural relaxations of sapphire remain suppressed.
