Variations of BR rate and the GR rate per unit cross-sectional area in the device with bias voltage when α = 1/ β = 1. The BR rate and the GR rate here are the integrals of BR rate and the GR rate of different positions in the device from anode to cathode, respectively. The inset shows the J – V curve when α = 1/ β = 1.
