About this tag
This tag covers discussions about charge transport in graphene nanoribbons, focusing on the electronic properties at their edges. Topics include scanning tunneling microscopy and spectroscopy used to study changes in electronic states from the interior to the edge of nanoribbons. The content references theoretical predictions from the 1990s about edge states and experimental observations by physicists at Lawrence Berkeley National Laboratory. Discussions involve atomic-scale characterization of graphene, a carbon honeycomb lattice one atom thick, and its unique electronic behavior relevant to materials science and nanotechnology.

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
