论文摘要
新的透视图立方准合金CDO/MGO短期超晶格在蓝宝石底物上通过等离子体辅助分子束的外观外观增长。使用高分辨率X射线衍射（HRXRD）和透射电子显微镜（TEM）技术来表征它们的晶体质量。提取了MGO和CDO层的厚度和生长速率。明确观察到了与0.6至5 nm的超晶格周期相对应的小角度X射线衍射峰。从XRD测量值中，我们在样品A（CDO/MGO -4.7 nm/1 nm）中获得了65％的弛豫，对超晶格（SL）的底物（SL）的底物，在样品B（CDO/MGO -2 nm/4 nm）中的SL放松96％。 SL的表面粗糙度参数是通过小角度X射线衍射和原子力微拷贝研究获得的。
New perspective cubic quasi-alloys CdO/MgO short period superlattices were grown on sapphire substrates by plasma assisted molecular beam epitaxy. Their crystal quality was characterized using High Resolution X-ray Diffraction (HRXRD) and Transmission Electron Microscopy (TEM) techniques. The thickness and growth rate of MgO and CdO individual layers have been extracted. Small angle X-ray diffraction peaks corresponding to the period of the superlattices ranging from 0.6 to 5 nm were clearly observed. From the XRD measurements we obtain 65% relaxation to the substrate of superlattice (SL) in Sample A (CdO/MgO - 4.7 nm/1 nm) and 96% relaxation of SL in Sample B (CdO/MgO - 2 nm/4 nm). Surface roughness parameters for SL were obtained both by Small angle X-ray diffraction and Atomic Force Microcopy studies.
