Static Local-Field Correction In Electron-Electron Quantum Bilayers

We present a numerical calculation for the intra- and inter layer local-field correction factors, G(II), (q,0), with unequal density, of coupled electron-electron quantum bilayer system. The are calculated within the framework of quantum self-consistent mean-field approximation of Singwi, Tosi, Land and Sjolander (qSTLS) as a function of layer parameters. We found that intra layer local-field correction factor yields pronounced oscillatory behavior with different layer parameters. The results are compared with G(II)(q,0) of recent findings of the equal density effects in electron-electron quantum bilayer systems and G(q,0) of isolated single quantum layer.
