Distance dependent transport properties on a vertical heterojunction.
(a) SEM image of a graphene-BNNT heterojunction as contacted across by two STM probes at conduction distance, d = 1.23 μm. (b,c) The corresponding current-voltage (I-V) characteristics at a series of d. (d,e) Linear and log scale of current flow across the heterojunction as a function of distance, d as extracted from Fig. S8. (f) The source-drain currents across the heterojunction as a function of back gate voltages.
