Abstract
A square graphene single electron transistor SET was defined with two side gates and its transport was studied at low temperature at T = 2 K At zero magnetic field Coulomb blockade oscillations were clearly observed near the Dirac point of this device At high magnetic field in the quantum Hall regime we observed ballistic tunneling of the carriers through the graphene SET contrary to the Coulomb blockades observed while approaching the vicinity of the Dirac point
