We present a numerical calculation for the drag resistivity of charge carriers interaction in coupled layer system separated by a barrier. Analytical expressions of non-linear susceptibility function and effective interlayer Coulomb interaction have been shown for non homogeneous dielectric environment at low temperature and low frequency regime. The system is studied within the model of random phase approximation (RPA) and taking into account the static local field correction (LFC). We employ Hubbard approximations (HA) and self consistent STLS approximations based LFC for obtaining the results, where LFC includes the exchange and correlation effects. Exchange and correlation effects enhanced the drag resistivity and the net screening. Another important quantity is the local form factors (LFF), which is the function of the bare inter- and intra-layer potential of the dielectric media. LFF for a multi-layer system is derived from the Poisson equation solution.

我们为耦合层系统中被势垒隔开的电荷载流子相互作用的阻力阻力提供了一个数值计算方法。非线性磁化率函数和有效的层间库仑相互作用的解析表达式已在低温和低频条件下的非均匀介质环境中得到了证明。在随机相位近似（RPA）模型中研究了该系统，并考虑了静态局部场校正（LFC）。我们使用基于LFC的Hubbard近似（HA）和自洽STLS近似来获取结果，其中LFC包括交换效应和相关效应。交换和相关效应增强了抗阻性和网状筛选。另一个重要的数量是局部尺寸（LFF），这是电介质裸层间和层内电势的函数。多层系统的LFF是从Poisson方程解得出的。
