Abstract

Abstract By making explicit use of the so-called ‘Kambe structure constants’, originally formulated for a theoretical description of low energy electron diffraction (LEED), the screened KKR surface Green's function (SKKR-SGF) method for layered systems can conceptually be extended to inultilayer systems corresponding to complex two-dimensional lattices and to layer relaxation at interfaces (surfaces). In the present paper the screening properties of the ‘Kambe structure constants’ are illustrated.
