X-RAY DOUBLE-CRYSTAL DIFFRACTION OF SUPERLATTICES AND ITS COMPUTER SIMULATION
超晶格结构的X射线衍射拟合计算

By using the X-ray diffraction kinematical theory which assumes ideally sharp interfaces, with computer simulation calculation, the accurate values of (GaAlAs)_m(GaAs)_n/GaAs(001) one-dimensional superlattice structure parameters have been obtained. In addition, the influence of asymmetry of the satellite peak intensity and the presence of the transition layer and the strain has also been analyzed and discussed.
