I am researching on the synthesis of transition-metal dichalcogenides (TMDs), but they appear obvious phenomenon of stacking fault. What practical significance do stacking fault would have for materials?
The stacking faults and twins may strenghen soft metals when the thickness of stacking faults is below a critical value. In your case, these stacking faults are growing planar defects, these is no significant effects on the propers except that high density of stacking faults will inhibitate movment of dislocations.
