This study is devoted to the problem of electronic transport in graphene nanodevices in 4-terminal systems with various arrangements of electrodes. The electrodes are attached to square and rectangular graphene nanoflakes with armchair (a) and zigzag (z) edges. Apart from the known case of the zzzz-configuration, with all the electrodes coupled to the zigzag fragments of the edges, also the aaaa- and zaza-type cases are considered here. The adopted theoretical approach is based on a tight-binding method combined with the wideband approximation for electrodes, and an effective iterative knitting-type Green's function algorithm.
