Narrow gaps are formed in suspended single to few layer graphene devicesusing a pulsed electrical breakdown technique. The conductance of the resultingdevices can be programmed by the application of voltage pulses, with a voltageof 2.5V~4.5V corresponding to an ON pulse and voltages ~8V corresponding to OFFpulses. Electron microscope imaging of the devices shows that the graphenesheets typically remain suspended and that the device conductance tends to zerowhen the observed gap is large. The switching rate is strongly temperaturedependent, which rules out a purely electromechanical switching mechanism. Thisobserved switching in suspended graphene devices strongly suggests a switchingmechanism via atomic movement and/or chemical rearrangement, and underscoresthe potential of all-carbon devices for integration with graphene electronics.
