Methods for determining the depth of
nanoholes in metal aluminum at its high-voltage anodization
Abstract
Two alternative
approaches to determining depth of nanopores (nanoholes) formed on metallic
aluminium during its high-voltage anodizing were suggested. The first approach
consists in electron microscopic examination of a cut metal layer by ion
cutting using a sprayed protective platinum layer, which allows direct
observation of an array of nanopores. The second approach is an indirect one,
and it consists in creating of copper replicas from a metallic aluminium layer,
followed by electrochemical determination of total surface of copper electrode
and calculation of copper nanowool height. The two approaches are shown to lead
to the same results.
Key words: copper nanostructures,
voltammetry, aluminum anodizing, scanning electron microscopy.
