Abstract:
Polyfurfural thin films lying in the thickness range of 1300–2000 A˚ were prepared by ac plasma polymerization technique.
The current–voltage characteristics in symmetric and asymmetric electrode configuration were studied with a view to determining
the dominant conduction mechanism.It was found that the Schottky conduction mechanism is dominant in plasma polymerized
furfural thin films.The predominance of Schottky mechanism was further confirmed based on the thermally stimulated current
measurements.

Abstract:
A novel fibre optic sensor for the in situ measurement of the rate of deposition of thin films has been developed. Evanescent wave in the uncladded portion of a multimode fibre is utilised for this sensor development. In the present paper we demonstrate how this sensor is useful for the monitoring of the deposition rate of polypyrrole thin films, deposited by an AC plasma polymerisation method. This technique is simple, accurate and highly sensitive compared with existing techniques.
