Electronic transport properties on V-shaped-notched zigzag graphene nanoribbons junctions

► Spin-dependent electronic transport on V-shaped notched ZGNRs junctions. ► The effects of armchair and zigzag notches on ZGNRs have been considered. ► The currents will be reduced for notched systems. ► The spin-up and spin-down display different behaviors. ► The transport will be suppressed and NDR behaviors can be observed.
