A self-consistent surface Green-function (SSGF) method for the calculation of isolated adsorbate atoms on a semi-infinite crystal

Abstract
This paper describes a computer code for total-energy and electronic structure calculations of an isolated adsorbate atom on a metal surface using a self-consistent surface Green-function method. The approach is based on density-functional theory together with the local-density approximation of the exchange-correlation functional. The method allows to calculate the adsorption problem on an atomistic, semi-infinite metal surface. The code does not rely on particular symmetries of the surface o...

Nature of problem
The computer code allows to calculate the Green function of an adsorption problem with a single, isolated adsorbate atom (so-called "adsorbate system") on a semi-infinite metal surface. The following physical quantities are available as output: change in electron density for the adsorbate system, change in density of states, total energy of the adsorbate system, and the Hellmann-Feynman forces on the adsorbate atom. The program uses density-functional theory within the local- density approximati ...
