Contact resistivity and current flow path at metal/graphene contact [PDF]
Applied Physics Letters, 2010 The contact properties between metal and graphene were examined. The electrical measurement on a multiprobe device with different contact areas revealed that the current flow preferentially entered graphene at the edge of the contact metal. The analysis using the cross-bridge Kelvin (CBK) structure suggested that a transition from the edge conduction ...
