The single-particle dynamical properties of a strongly coupled, classical, symmetric electronic bilayer system have been investigated by molecular dynamics simulation. Results for the velocity correlation function, the single-particle scattering function, and their respective Fourier transforms have been calculated, and their behavior, as a function of the interlayer separation d, has been analyzed. The single-particle scattering function in particular, shows dramatic effects when the bilayer attains a staggered square lattice structure. This occurs when the interlayer separation is around 0.8a (a is the Wigner-Seitz radius), where our previous study showed a marked decrease in the diffusion coefficient.
通过分子动力学模拟研究了强耦合经典对称电子双层系统的单粒子动力学性质。计算了速度关联函数、单粒子散射函数及其各自的傅里叶变换的结果，并分析了它们作为层间间距d的函数的行为。特别是单粒子散射函数，当双层达到交错方形晶格结构时显示出显著影响。这种情况发生在层间间距约为0.8a（a是维格纳-赛茨半径）时，我们之前的研究表明此时扩散系数显著降低。
