On the basal plane
Web4 de ago. de 2024 · Normally, however, pure c ⇀ dislocations were usually bounded on the basal plane rather than prismatic planes [6], [7]. It was thus highly probable that the dislocations lying on the ( 01 1 ¯ 0 ) plane belonged to a ⇀ + c ⇀ screw type, which was initially activated on the ( 2 1 ¯ 1 ¯ 2 ) plane (highlighted in yellow) and intersected with ( … Web28 de fev. de 2024 · Basal-plane dislocations (BPDs) pose a great challenge to the reliability of bipolar power devices based on the 4H silicon carbide (4H-SiC). It is well established that heavy nitrogen (N) doping promotes the conversion of BPDs to threading edge dislocations (TEDs) and improves the reliability of 4H-SiC-based bipolar power …
