摘要：
A model for a layered electron system is developed in which the electrons are treated completely quantum mechanically. In this model the ionic cores are replaced by parallel sheets of uniform positive charge. These charged sheets provide the neutralizing charge and the external potential which confines the interacting electrons in the local-density-functional calculation of the ground-state system. The plasma excitations of this model are obtained in a self-consistent calculation using the time-dependent local-density approximation.
