H. Masuda et al., Self-repair of ordered pattern of nanometer dimensions based on self-compensation properties of anodic porous alumina, APPL PHYS L, 78(6), 2001, pp. 826-828
The self-repair of an ordered pattern of nanometer dimensions based on the
self-compensation properties of anodic porous alumina is demonstrated. In a
pretextured pattern formed on Al using the nanoindentation process with an
array of convexes, the deficiency sites of the pattern were found to be co
mpensated automatically during the anodization. Combining the self-compensa
tion properties of the pore configuration of the anodic porous alumina with
the preparation of a replica of the compensated porous structure allowed u
s to develop a process which has the capability of self-repairing the imper
fections in the starting pattern. It was confirmed that deficiencies in the
starting pattern could be repaired automatically in the Ni pattern regener
ated using the self-compensated anodic porous alumina as a template. (C) 20
