WebNov 14, 2024 · Typical RBS/C spectra for the a-plane GaN sample implanted using different Ar-fluences are shown in Figure 2a. The backscattering yield of the as-grown sample is very low. Minimum yields well below 2% were measured close to the surface for all three sample materials, evidencing excellent crystalline quality along the growth direction. Webing Rutherford backscattering and channeling spectrometry (RBS/C), with a 1.57 MeV HeCbeam and two detectors at backscattering angles of 168 and 105 . The 168 backscat-tering geometry was used to characterize the channeling minimum yield ˜min along the [0001] axis. ˜min is the ratio of the backscattering yield with the incident beam aligned ...
