(a) HRSTEM image of the area outlined by green box in Fig. 4(a). (b) Schematic illustration of the possible Burgers vectors viewed along [10
] direction. (c) The same image as in Fig. 5(a) viewed along [11
] direction. (d) Schematic diagram illustrating the possible Burgers vectors viewed along [11
]. Combining (b) with (d), only Burgers vector b = a[0
1] is possible.
