Figure 3. EFTEM and SAED investigations on AG-GaN 3D hybrid network.

(a) Zero loss peak TEM image of a tubular Aerographite arm partially coated with GaN nano- and microstructures. (b)–(d) Corresponding EFTEM maps of gallium, nitrogen, and carbon indicating the formation of GaN onto AG. (e) SAED pattern along the zone axis [321] of GaN recorded from the circled area in the ZLP-TEM image. (f) Kinematic simulation of the [321] axis pattern.
