KEYWORDS

Adsorption barium hafnium structural model dipole work function coating

 

ABSTRACT

The adsorption process of barium atoms on hafnium is considered. A structural model of the system is presented and on the basis of calculation of interaction between ions dipole system the dependence of the work function on the coating.
