Omega-2theta
WebIntroduction to HRXRD - Massachusetts Institute of Technology Web15. jun 2024. · The omega-2theta scans for growth J (Fig. 6 d) indicate almost identical compositions for GaAsP layers grown on the planar sample (x = 0.22) and the textured sample (x = 0.21). These composition values are notably different from the GaAsP grown on GaAs substrate in growth B, which is × = 0.18 ( Fig. 2 a), despite using the same growth ...
