abstract = {The design of two dimensional graphene-type materials with an anisotropic electron flow direction in
the X- and Y-axes opens the door for the development of novel electronic materials with multiple
functions in nanoelectronics. In the present work, we have studied the electronic transport properties
of a new family of 2D graphene–graphyne hybrids presenting conformationally free phenylethylene
subunits. This system ensures two different conductive pathways that are perpendicular to each other:
an acene nanoribbon subunit, in the X-axis, with graphene-type conduction, and a free to rotate
phenylethylene subunit, in the Y-axis, in which the magnitude of the conduction depends dynamically
on the corresponding torsion angle. Our calculations have confirmed that this system presents two
different conduction pathways, which are related to the presence of asymmetric Dirac-type cones.
Moreover, the Dirac cones can be dynamically modified in the presence of an external gate electrode,
which is unprecedented in the literature.},
