WebApr 11, 2024 · For pure NiMn solid solution, an increase in the number of stacking faults results in more dislocations to be generated, as shown in Fig.10 (a) and Fig.10 (b). Besides, compared with the dislocation line length in Fig.10 (b) and Fig.10 (c), the total dislocation line length and shockley dislocation line length are increased significantly … http://li.mit.edu/A/Papers/04/Xu04.pdf Stacking faults are two dimensional planar defects that can occur in crystalline materials. They can be formed during crystal growth, during plastic deformation as partial dislocations move as a result of dissociation of a perfect dislocation, or by condensation of point defects during high-rate plastic … See more In crystallography, a stacking fault is a planar defect that can occur in crystalline materials. Crystalline materials form repeating patterns of layers of atoms. Errors can occur in the sequence of these layers and are … See more Stacking faults can be visualized using electron microscopy. One commonly used technique is transmission electron microscopy (TEM). The other is electron channeling contrast imaging (ECCI) in scanning electron microscope (SEM). In an SEM, near … See more Many compound semiconductors, e.g. those combining elements from groups III and V or from groups II and VI of the periodic table, crystallize in the fcc zincblende or hcp wurtzite crystal structures.
