形(应)变超晶格的沟道效应与系统的相平面特征 总被引:13,自引:4,他引:9
利用正弦平方势,把粒子运动方程化为具有δ力矩的摆方程.分析了无扰动系统的相平面特征,计算了扰动系统的退道效应.讨论了退道系数与晶格形变之间的关系.The particle motion equation has been reduced to the pendulum equation with a δ moment by using sine squared potential. The phase planar characteristics have been analysed for a non perturbed systeam . The dechanneling effects have been calculated numerically for a perturbed system. The relationship between the dechanneling fraction and superlattice deformation in resonance has been discussed. 相似文献
