“…However, it is most likely attributed to BSFs of type I 2 29 or prismatic stacking faults, 27,30 which can arise from folded BSFs with stair-rod dislocations at their intersections. 8,30 Now, as we mentioned above, there are high densities of stacking faults in our heteroepitaxial samples. Therefore, it is reasonable to assume that not only the GaN emission but also the QW emission is influenced by the stacking faults.…”

“…[5][6][7] However, most of these structures were affected by high densities of threading dislocations (TDs) and basal plane stacking faults (BSFs), which are terminated by either prismatic stacking faults (PSFs) or partial dislocations. 8 While TDs are known to act as nonradiative recombination centers, BSFs are optically active since they can be considered as cubic (zincblende) ABC phases in the wurtzite ABAB stacking sequence. Such a structure forms a type-II heterojunction which may capture electrons and holes resulting in optical transitions below the wurtzite GaN bandgap energy.…”

“…Therefore, the significant reduction in BSF density in sample AG4 can be explained by the increase in the 3D-2D transition stage. Meanwhile, BSFs are found to be terminated by PDs or prismatic stacking faults (PSFs) [21]. In particular, BSFs are predominantly terminated by PDs because the density of PSFs (R = 1/2<1011>) formed on prismatic {1210} planes is much lower (~10 2 cm -1 ) than the density of PDs.…”
