New technique tunes into graphene nanoribbons’ electronic
potential

Ever since graphene—a thin carbon sheet just one-atom
thick—was discovered more than 15 years ago, the wonder material
became a workhorse in materials science research. From this body of
work, other researchers learned that slicing graphene along the
edge of its honeycomb lattice creates one-dimensional zigzag
graphene strips or nanoribbons with exotic magnetic
properties.
