WebMar 1, 1996 · TDs originated from GaN/sapphire interface were fully blocked away from device-active region. In c-GaN case, excellent CL intensity at 365 nm wavelength and … WebMar 1, 2024 · GaN was grown on cone- and dome-patterned sapphire (CPSS and DPSS) at different nucleation times of 40, 80 and 160 s. The GaN was also grown on flat sapphire substrate (FSS) for comparison. The results showed that the GaN growth improved by increasing the nucleation time, except for the case of FSS. Compared to CPSS, DPSS …
