We have realized nanometer size constrictions in ballistic graphenenanoribbons grown on sidewalls of SiC mesa structures. The high quality of ourdevices allows the observation of a number of electronic quantum interferencephenomena. The transmissions of Fabry-Perot like resonances were probed byin-situ transport measurements at various temperatures. The energies of theresonances are determined by the size of the constrictions which can becontrolled precisely using STM lithography. The temperature and size dependenceof the measured conductances are in quantitative agreement with tight-bindingcalculations. The fact that these interference effects are visible even at roomtemperature makes the reported devices attractive as building blocks for futurecarbon based electronics.
