Avalanche Breakdown in Epitaxial SiC p-n Junctions

Abstract
The reverse current‐voltage characteristics of epitaxial SiC p‐n junctions were investigated. After electrolytic etching the junctions showed sharp breakdown. The largest value found for the maximum field at breakdown is 5×106 V/cm. Microplasma pulses were observed analogous to but three orders‐of‐magnitude smaller than those hitherto reported for other materials.
