Ground state of a quasi-two-dimensional electron gas

Original · EN

We consider the three-dimensional electron gas confined by a strictly two-dimensional homogeneous positive charge density at z=0. Within the Hartree-Fock approximation, we study the mode structure in the confined direction in the metallic regime. We find, that for rₛ<1.3 (rₛ<2.5) the unpolarized (polarized) electron gas starts to populate also the first excited state in the z-direction.
