WebJul 1, 2002 · Stacking-fault growth in SiC PiN diodes has been examined using light-emission imaging and stressing at 80 A/cm2 and 160 A/cm2. Dark areas in the emission develop because of stacking faults and the current capability of the diode drops. More detailed images are produced by reducing the current by a factor of 1000. The low-current … WebJan 1, 2006 · A similar mechanism would operate in the PVT growth of SiC bulk crystals, which can convert TSDs into basal plane defects such as stacking faults. As shown in Fig. 1, foreign polytype inclusions terminated the propagation of TSDs. This process is likely to be a process involving the conversion of TSDs into stacking faults.

WebJun 1, 2024 · A basal plane dislocation is a killing defect in SiC bipolar devices because a Shockley-type stacking fault (SSF) is expanded from the dislocation when the electron-hole recombination energy is given. After classification of SSF-expansion patterns, the major types of SSFs (triangular-shaped and bar-shaped SSFs) and their origins are identified. WebSep 13, 2024 · A triangular single Shockley stacking fault (1SSF) in 4H-SiC, expanding from the surface to the substrate/epilayer interface, was investigated. The triangular 1SSF was observed during electroluminescence examination of PIN diodes that had line-and-space anodes with open windows. The threshold current density of the 1SSF expansion was …
