Description
M Amir Bazrafshan, Farhad Khoeini, and Bartłomiej Szafran study how edge shape affects transport in round graphene devices. Published in 2024, the work looks at disks and rings of graphene with Klein edges. The team changed the inner and outer radii and used a Green's function method for systems out of balance.
At small radii, armchair Klein edges helped keep electron transport from dropping, while zigzag edges cut the transmission sharply. That split shows the edge atom pattern matters a great deal. The outer radius shaped electron flow in a more regular way than the inner radius. For phonons, the heat carrying vibrations, no clear edge pattern stood out at the sizes tested.
