From left to right: cross-section high-angle annular dark-field STEM of an exemplary GaN NW on diamond substrate; tilted-view SEM images of as-grown GaN NWs on diamond (top), HRTEM image of the interface region (bottom); temperature-dependent PL spectra of GaN NWs on diamond with typical NBE shift due to band gap shrinkage [13]; selective area grown GaN NW arrays without (top) and with a hole (bottom) [50].
