Abstract

We calculate the Hartree, exchange and correlation energies of a quasi-2D electron gas in a semiconductor quantum well as an expansion in Coulomb interaction. This allows us to get the well width dependence of these energies analytically. This also shows that such an expansion is quite valid for the Hartree term in usual experimental situations (electrons in the lowest subband only and well width smaller than the Bohr radius).
