Gas sensitivity of individual nanostructures based on functionalized multi-walled carbon nanotubes and metal oxides
Using the methods of scanning force microscopy, the gas sensitivity properties of individual composite nanostructures based on CNTs, functionalized by argon ions and coated with tin and titanium oxides are investigated. The Fermi level shift and the change in longitudinal conductivity upon absor...

| description | Using the methods of scanning force microscopy, the gas
sensitivity properties of individual composite nanostructures
based on CNTs, functionalized by argon ions and coated with tin
and titanium oxides are investigated. The Fermi level shift and
the change in longitudinal conductivity upon absorption ammonia
and nitrogen dioxide are determined. It is shown that the change
in conductivity of the composite nanostructures to the correlates
with the Fermi level shift under gases exposure as a result of
charge carriers concentration changing in the metal oxide surface
layers upon adsorption of gas molecules. |
