Book chapter

Halogen adsorption on metals

B. V. Andryushechkin.

This chapter presents a review of the experimental and theoretical investigations of halogen interaction with metal surfaces. The emphasis is on the recent measurements performed with scanning tunneling microscopy in combination with density functional theory calculations. The surface structures formed on metal surface after halogen action are classified into three groups: chemisorbed monolayer, surface halide, bulk-like halide. Formation of monolayer structures is described in terms of surface phase transitions. Surface halide phases are considered as intermediates between chemisorbed halogen and bulk halide. The general conclusion is that, for a number of systems, the picture of halogen/metal interaction is still far from complete.
