摘要

A novel Schottky contact super barrier rectifier (SSBR) with a top N-enhancement layer and a P-injector (P-TNEL-SSBR) is proposed and investigated by simulation. In addition to the concept of SSBR we presented recently, the proposed P-TNEL-SSBR has an extra P-injector structure and a top NEL design (INEL, a modified structure of the N-enhancement layer we proposed earlier). The P-injector structure makes this new rectifier have the conductivity modulation effect by hole injection at large forward current densities which will be helpful for surge current capability. The INEL decreases the barrier capacitance during the reverse recovery state and weakens the JFET effect further in the forward conducting state. Simulation results show that, with almost the same reverse leakage current density and breakdown voltage of approximately 57 V, P-TNEL-SSBR increases the figure of merit (FOM, equates to V-B(2)/R-on,R- sp) by 11.1% at the forward current density of 200 A/cm(2) and decreases the reverse recovery time by 13.3% at the reverse voltage of 12 V compared to those of NEL-SSBR we reported earlier.
