Study of the charge transfer process in the polyaniline/graphite heterojunction by conductive atomic force microscopy
Thin layers of polyaniline on the surface of highly oriented pyrolytic graphite are obtained by in-situ chemical oxidative polymerization of aniline. The current-voltage characteristics of the tip/polyaniline/graphite contact, which have a form characteristic of tunnel contacts, have been measur...

| Summary: | Thin layers of polyaniline on the surface of highly oriented
pyrolytic graphite are obtained by in-situ chemical oxidative
polymerization of aniline. The current-voltage characteristics
of the tip/polyaniline/graphite contact, which have a form
characteristic of tunnel contacts, have been measured by the
method of conducting atomic force microscopy. By modeling
the current-voltage characteristics using the Simmons model,
the width of the potential barrier is determined, which for the
investigated heterojunction is 0,5 nm. |
