TEM images of a typical GaAs nanowire: (a) HRTEM image of a pure wurtzite (WZ) structure region with a simulation of the atom positions overlaid; (b) bright-field image of the top part of the NW; (c) HRTEM image of a zinc blende structure (ZB) region with twin planes (T) and stacking faults (SF); (d) schematic diagram of the atomic stacking for zincblende structure with twin planes and stacking faults as shown in (c).  [article HTML]
