From a Five-Layer Graphene Sandwich, a Rare Electronic State Emerges

After graphene was identified and isolated in 2004, the 2010 Nobel Committee wrote that “carbon, the basis of all life on earth, has surprised us once again.” Indeed, graphene has surprised us yet another time: MIT physicists have discovered that when graphene is stacked in five layers, it takes on a rare “multiferroic” state in which the material demonstrates both unconventional magnetism and an exotic type of electronic behavior which the team has coined ferro-valleytricity. “The discovery,” reports MIT, “could help engineers design ultra-low-power, high-capacity data storage devices for classical and quantum computers.” LTEOIL expects that its high-quality carbon nanosheets will be ideally suited for the creation of such compounds, which are difficult to achieve through the graphene created by existing processes.
