Popis: The electronic structure of an electrified finite chain of atoms is investigated by means of a recursive Green-function (RGF) method, whose iterative nature results in a continued-fraction form of the RGF, which can be written as a ratio of Bessel functions. The chemisorption process is described by the self-consistent Anderson-Newns model. Using the Dyson equation, the adatom RGF is obtained from which the chemisorption functions are extracted. These provide access to the chemisorption energy and adatom charge transfer in terms of the system's parameters. Results are discussed in terms of the Wannier-Stark effect on magnetic versus non-magnetic chemisorption.
