摘要: Electron-radiation-enhanced glide of 30°-Si(g) partial dislocations bringing about an expansion/shrinkage Shockley-type stacking faults in 4H-SiC was observed in-situ by transmission electron microscopy. Geometrical kinks on partials did not migrate the dark, indicating that kink migration is enhanced irradiation. The direction reversible depending irradiation intensity, which can be interpreted terms a sign reversal driving force originating effective fault energy variable with intensity.
