| 中文摘要 | periodicity fluctuations of layer thickness and composition in a superlattice not only decrease the intensity, they also broaden the width of the satellite peaks in the x-ray diffraction pattern. in this letter, we develop a method that is dependent on the width of satellite peaks to assess periodicity fluctuations of a superlattice quickly. a linear relation of the magnitude of fluctuations, peak width and peak order has been derived from x-ray diffraction kinematical theory. by means of this method, periodicity fluctuations in strained (ganas)(1)(gaas)(m) superlattices grown on gaas substrates by molecular beam epitaxy have been studied. distinct satellite peaks indicate that the superlattices are of high quality. the n composition of 0.25 and its fluctuation of 20% in a strained ganxas1-x monolayer are obtained from simulations of the measured diffraction pattern. the x-ray simulations and in situ observation results of reflection high-energy electron diffraction are in good agreement.
