چکیده
1. The common-base emitter current In hot-electron transistors, the emitter/base junction should allow the injection of electrons into the graphene base. The emitter current is the source of all the electrons injected into the graphene base and it consists of two components: one component is due to Fowler-Nordheim tunneling, and the other component is due to thermionic emission (e.g. the current over the tunneling barrier and the leakage current through pin-holes). Although both of these components contribute to the total emitter current, the current through pin-holes does not contribute to the collector current.

We demonstrate vertical graphene-base hot-electron transistors (GB-HETs) with a variety of structures and material parameters. Our GB-HETs exhibit a current saturation with a high current on-off ratio (>10(5)), which results from both the vertical transport of hot electrons across the ultrathin graphene base and the filtering of hot electrons through a built-in energy barrier. The influences of...
