Abstract
The scientific interest has been focused not only on the
fabrication of various nano structured materials but also on
their industrial and technological applications.
Manufacturing of well-ordered nanostructures on the length
scales less than dozens nm by conventional optical lithography
is a great challenge. Automated microscopic image analysis
provides an efficient tool for qualitative analysis in modern
material science and biological studies. The main objective of
the present study is to develop an automatic tool to determine
the effect of time on nanopore structures formed via
electrochemical anodization of high purity Al2O3 films in
digital microscopic FE-SEM and EDX nano pore images.
Geometric shape features are used to measure the variance of
nano pore size depending on the chemical compounds,
namely, concentration (%), time (min), temperature (oC) and
voltage (V). The current methods rely on the subjective
reading of profiles by a human expert based on the various
manual staining methods. In this paper, an automated method
is proposed for the effect of time on nanopore structures
formed via electrochemical anodization of high purity Al2O3
films in digital microscopic nano pore images and extracting
geometric shape features for the growth of Al2O3 films. It is
observed that the regularity of nanopores arrangement can be
significantly improved by increasing anodizing time at
constant temperature and voltage, and after the anodizing
process, at every interval of time there is a significant
decrease in wall thickness from 58-26nm and increase in the
nanopore diameter size about 31-86 nm. The experimental
results are compared with the manual results obtained by the
chemical expert and demonstrate the efficacy of the proposed
method.
