• The feature of the Ag step decoration on air- and vacuum-cleaved NaCl crystals which are irradiated by low energy electrons before Ag deposition has been studied. In the case of air-cleaved NaCl, no step decoration is recognized on the surfaces irradiated with a considerable amount of electrons. The border line where the step decoration fads out completely coincides with a hyperbola I_e×t=260mA・sec (〜1x10^<15> electrons/cm^2 on the substrate surface), where I_2 is the emission current of the electron irradiator and t is the irradiation time. In the case of vacuum-cleaved NaCl, there is no region of complete disappearance of the step decoration in spite of the heavy irradiation. The changes in the Ag particle density and surface coverage in both cases are closely related to the amounts of I_e×t. The irradiated surface can be made to lose its function by the annealing treatment before deposition.
