About this tag
Scanning tunneling microscopy (STM) is a powerful technique for imaging surfaces at the atomic scale, as demonstrated in recent research on graphene nanoribbons. By using an STM, scientists can determine the topography and orientation of materials like graphene nanoribbons with atomic precision. In spectroscopy mode, STM reveals changes in the density of electronic states, from the interior to the edge of the nanoribbon. This capability has enabled physicists to confirm long-standing theoretical predictions about extraordinary electronic properties at the edges of graphene nanoribbons, advancing our understanding of quantum materials.

Electronic life on the edge: Scientists discover the edge states of graphene nanoribbons
A scanning tunneling microscope determines the topography and orientation of the graphene nanoribbons on the atomic scale. In spectroscopy mode, it determines changes in the density of electronic states, from the nanoribbon's interior to its edge. Credit: Crommie et al, Lawrence Berkeley...- cybercore
