Revealing the Remarkable Properties of Multilayer Graphene

Graphene, a material derived from ordinary pencil lead when shaved down to atomic layers, has demonstrated an array of extraordinary properties over the years. When stacked into five layers in a rhombohedral pattern, graphene exhibits a rare "multiferroic" state, combining unconventional magnetism and a unique form of electronic behavior known as ferro-valleytricity. This discovery,...
