Paper Abstract

In this paper we show the application of Rutherford backscattering spectrometry and ion channeling (RBS/C) for the detection of compositional and strain gradients in CdZnO grown almost pseudomorphically on MgZnO. The asymmetric features revealed in X-ray diffraction studies were explained by the compositional gradient found in the first 100 nm close to the interface. Calculations of the effect of such a gradient on the strain state of the layer were developed and contrasted with RBS/C angular scans. Additionally, the substitutional behavior of Cd (and Mg) in Zn-sites was demonstrated.
