Abstract
Cubic SiC layers grown on Si(110) contain a high density of widely spread and intersecting stacking faults. Weak-beam transmission electron microscopy has been used to determine the possible Burgers vectors of both widely spread Shockley partial dislocations and sessile partial dislocations in such films. Partial Shockley dislocations that restrict non-intersecting stacking faults were characterized, and a stacking-fault energy of 0.1 mJ m−2 was determined. Edge sessile dislocations with 1/6(110) and 1/3(001) Burgers vectors were identified at the stacking-fault intersections.
