Measuring Graphene's Conductance (IMAGE) Institute for Basic Science Caption (Left) Nanodevice structure to measure graphene's electronic properties. Graphene is sandwiched between two hBTN layers and the two electrodes (graphite and silicon). (Right) Conductance of single layer graphene at different voltages, showing the dip at around 350 mV.
