(a) Photo of the grown AlGaN/GaN on h-BN, (b) High resolution X-ray diffraction 2θ − ω scans of the grown AlGaN/GaN heterostructure on h-BN using Al0.14Ga0.86N as a nucleation layer (NL), the red curve is the measurement and the blue curve presents the simulation result. The inset is a schematic of the grown structure. (c) High resolution TEM image showing the interface between the 2D layered h-BN and the AlGaN nucleation layer. (d) Energy dispersive X-ray spectroscopy (EDX) elemental mapping of Al.
