With an increase in the amount of Fe catalyst, the average crystallite size of the SiC particles increased, whereas the stacking fault density and the surface area decreased. 而使用Fe催化剂制成的干凝胶则可形成-βSiC。此外,随着Fe用量的增加,-βSiC的颗粒尺寸和平均晶粒度增加,而堆积缺陷密度和比表面积则减小。
Reduction of Stacking Fault Density(SFD) in Cubic GaN Epilayers via Epitaxial Lateral Overgrowth 用侧向外延生长法降低立方相GaN中的层错密度
Sub-structure of low carbon lath martensite is high density dislocation and stacking fault. high carbon martensite sub-structure is high density dislocation and a large amount twin crystal. 低碳板条状马氏体的亚结构为高密度位错+层错;高碳马氏体亚结构为高密度位错和大量精细孪晶。
