Forward current density

WebJul 10, 2024 · In this paper, the design and fabrication of GaN p-n diodes with breakdown voltages above 1.6 kV, in a process scalable to forward currents in excess of 12 A, and specific on-resistances of 0.15 mΩ cm 2 is reported, resulting in a BFOM of 18.8 GW/cm 2. These results demonstrate device performance very close to the fundamental limits of GaN. WebSep 13, 2014 · 1. In a PN junction diode, the reverse saturation current is due to the diffusive flow of minority electrons from the p-side to the n-side and the minority holes from the n-side to the p-side. Hence, the reverse saturation current depends on the diffusion coefficient of electrons and holes. The minority carriers are thermally generated so the ...

WebMar 26, 2024 · Thus, from the minority carrier density at the boundary of the depletion zone, we can calculate the rate of diffusion of the minority carriers, which is (approximately) the current density, and from that we can calculate the total current of that type of carrier. A depletion region forms instantaneously across a p–n junction. It is most easily described when the junction is in thermal equilibrium or in a steady state: in both of these cases the properties of the system do not vary in time; they have been called dynamic equilibrium.
