Illustration of the back-to-back diode measurement setup and back-to-back Al/Al2O3/SiC diode measurements. (a) Illustration of the back-to-back diode measurement setup where only the reverse current is measured. (b) Back-to-back Al/Al2O3/SiC diode measurements demonstrating the effective modulation of current density by the thickness of Al2O3.
