Abstrakt: It is shown that depositing Bi on an Si(001) surface fills the free broken-bond surface states, whose concentration decreases linearly as the bismuth coating 8 increases up to ?st, = 0.6 monolayer. The bismuth desorption activation energy is constant ? < ?st, (Ed = 2.77 ± 0.1 eV) and decreases for ? > ?st.
