Transparent conducting oxides (TCO's) have drawn great attention owing
to their high electrical conductivity (10,000 S/cm) and high
transparency (80-90%) in the visible region. This combination of
properties makes them suitable for a number of applications such as
solar cells, LCD display, OPV devices and even transparent electronics.
The TCO nanostructures even showed better transparent contact than TCO
thin film. High surface-to-volume ratio of nanostructures have
demonstrated high sensitivity towards various target gases like NH3, CO,
H2 and H2S and for NO2, which is one of the most dangerous air
pollutants that causes acid rain and holes in ozone layer. To realize
these applications, a basic understanding of the growth mechanism of
nanostructures is a key requirement. Here, the main focus is given for
tunable growth of indium oxide nanostructures and their applications.
The indium metal filled indium oxide nanotube based nanorocket and
indium mass transport in indium oxide nanotubes is demonstrated with the
help of high-resolution transmission electron microscopy.
