Abstract
Superfluid ground stars in the electron-hole double lager systems is i nvestigated within the mean field approach at zero temperature. The si ngle particle excitation spectrum is obtained for various densities an d barrier widths separating the layers. The electron-hole pairing gap is shown to be significantly reduced by the dielectric screening shift ing the most favourable conditions for the condensation towards lower carrier concentrations.
