Figure 2
Structural and optical properties of GaN film on Hf foil with a LT-grown reaction barrier layer. (a) Surface SEM and (b) cross-sectional TEM images of the GaN film. Inset of (a) is a surface AFM image. (c) EBSD pole figures of {0001}GaN and \(\{11\overline{2}4\}\) GaN. (d) 0002 and \(10\overline{1}2\) XRCs, and (e) a RT-PL spectrum of the GaN film.
