Breakdown field in vapor-grown silicon carbide p-n junctions

Abstract
The electrical breakdown of one‐sided abrupt pn junctions in 6H silicon carbide has been investigated. The diodes are produced by vapor growth and mesa etching. Breakdown fields in the range (2–3.7) ×106 V/cm have been observed for p layers with 1017<NA18 cm−3. These figures tend to support the results of van Opdorp and Vrakking.
