Abstract
We propose a simple analytical expression for the inter-layer local-fi eld correction (LFC) for weakly coupled two-layer systems and develop a sum-rule version of the self-consistent approach of Singwi, Tosi, La nd, and Sjolander. On the basis of the approximate approach, the inter -layer LFC is investigated for electron-electron and electron-hole lay ers with different carrier densities and layer spacings. Using this pa rametrized inter-layer LFC, we calculated the transresistance in the e lectron-electron and electron-hole layers. The theoretical results are in good agreement with the available experimental data.
