Propagation stacking fault
WebStacking faults within 4H-SiC PiN diodes are known to be detrimental to device operation. Here, we present electroluminescence (EL) images of 4H-SiC PiN diodes providing evidence that electrically and optically stimulated Shockley stacking fault (SSF) propagation is a reversible process at temperatures as low as 210°C. Optical beam induced current (OBIC) … WebMay 1, 2024 · It is shown that those stacking faults result from the operation of "composite" dislocation core structures. It is demonstrated that such cores allow for the propagation …

WebPropagation may take place on a single fault, but in many cases the rupture starts on one fault before jumping to another, sometimes repeatedly. The 2002 Denali earthquake initiated on a thrust fault, the Sutsina Glacier Thrust, before jumping onto the Denali Fault for most of its propagation before finally jumping again onto the Totschunda Fault. WebApr 11, 2024 · There are single dislocations and stacking faults at the edges; however, the high density of dislocations traversing along the <111> direction as observed in type Ib crystals is absent. There are polishing lines, traversing along the diagonal direction, present on the surface of the plate as shown in Figure 6 b.
WebStacking faults are surrounded by partial dislocations that facilitate the faults joining smoothly with the nonfaulted regions within the crystal structure. The faults occur on {111} planes in the crystal. Metallic-decorated partial dislocations can cause electrical degradation if they cross p–n junctions.
