Ag(001) or Ag(111) at between 300 and 65K. The growth on all of these surfaces exhibited a consistent trend towards a large compressive strain that was attributed to the incorporation of vacancies into the growing film below 160K. In each case, the vacancy concentration was about 2% at 110K and the temperature dependence for incorporation onto the (001) surfaces was measured; as well as the annealing behavior of Cu(001). These results suggested the operation of new kinetic mechanisms.
