From: Switching Behaviors of Graphene-Boron Nitride Nanotube Heterojunctions
Distance dependent transport properties on a horizontal heterojunction and the schematic of DOS mismatch.
SEM images of a horizontal graphene-BNNT heterojunction as contacted across by two STM probes (a) and the current-voltage (I-V) characteristics (b,c) at d = 0.73 μm and d = 0.64 μm. Schematic drawing of a vertical heterojunction (d) and horizontal heterojunction (e) indicate the locations of DOS mismatch.
