In the past decade 2D materials have captured the fascination of a steadily increasing number of scientists. These materials, whose defining feature is having a thickness of only one to very few atoms, can be made of a variety of different elements or combinations thereof. Scientists’ enchantment with 2D materials began with a winning experiment: creating a 2D material using a lump of graphite and common adhesive tape. This ingeniously simple experiment yielded an incredible material: graphene.
