Studying the Conduction Mechanism of 5- Methoxy Indole -2 , 3- Dion (5- Methoxy Isatin) Films.

الملخص

The work described in this article is concentrated on the preparation and
analysis to examine the conduction mechanism of 5- methoxy Indole -2,3- dione
(5-Methoxy Isatin) films by condensation method .
Electrical measurements including (current- voltage) and (conductivity- temperature)
characteristics were studied in the temperature range (291- 343) K for specimens of
compact disk form . Aluminum electrodes were used to connect the specimens with
electrical circuit. Some related parameters namly electrical conduction of which the
values varied between 4.5x10 -10 to 2.7x10-9 s/ cm , trapping concentration (θ ) varied
between 23.07 to 8.8 and the activation energy ( Ea ) was 0.315 eV.
Hopping conduction mechanism seems to be the most probable of interpreting the
behavior of charge transport that is supplied by injection of electrodes
