Abstract

We report a new type of self-organized nanostructure for pure Ni and Fe thin foils irradiated with 400 keV electrons. Nanostructure develops at the electron exit surface of the foils. For Ni(001) irradiated along [001] direction at 105 K nanogrooves extend along [100] and [010] in the outer area of the beam, but the pattern differs from those near the beam center. For [011] irradiation, nanogrooves extend mainly along [100] direction and nanowires are finally formed. For Fe(111) irradiated along [111] at 300 K nanoholes are generated in the initial stage and then develop to a pattern of nanogrooves. The nanostructure is rather stable at temperatures lower than 823 K, although the evaporation from the specimen surface occurs.
