| Abstract: | A change in density of states is obtained by inclusion of intra-atomic interaction term to the mixing Hamiltonian constructed due to
chemisorbed adatoms with the clean metal surface. The double-time Green function
technique was employed in the Zubarev’s
equation of motion formalism and in order to decouple the hierarchy of
higher order Green functions Hartee-Fock decoupling approximation was assumed. From the
corresponding surface Green function, the modified density of states was
obtained through which chemisorption energy and energy of localization were
estimated and it was found that they
were of the same order as per the prediction |
