Abstract

The variational multicomponent hypernetted-chain scheme for the double-layer electron-electron and electron-hole systems developed by us is generalized to the case where the layers have finite thickness. We have also studied the elementary collective excitations and the region of stability of these systems as the layer separation is varied. In a single electron layer our result for the bulk modulus is in good agreement with the available experimental results.
