3 Oct 2007 | | Abstract: | Implicit and explicit density functionals for the exchange energy in finite
two-dimensional systems are developed following the approach of Becke and
Roussel [Phys. Rev. A {f 39}, 3761 (1989)]. Excellent agreement for the
exchange-hole potentials and exchange energies is found when compared with the
exact-exchange reference data for the two-dimensional uniform electron gas and
few-electron quantum dots, respectively. Thereby, this work significantly
improves the availability of approximate density functionals for dealing with
quasi-two-dimensional structures, which have various applications in
semiconductor nanotechnology. | | Source: | arXiv, 0710.0718 | | Services: | Forum | Review | PDF | Favorites | |
