摘要：
<正> An asymmetrically coupled ( GaAs/AlAs/GaAs/AlAs)/GaAs(001) double-well supperlattice isstudied by HRDCD (high resolution double-crystal X-ray diffractometry).The intensity of satellite peaks is modulated by wave packet of different sublayers.In the course of simulation,the satellite peaks in the vicinity of the node points of wave packet are very informative for precise determination of sublayer thickness and for improving accuracy.
