Studying the conduction mechanism of 5-methoxy indole-2, 3-dion (5-methoxy isatin)‎ films

Abstract EN

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 4.5 x 10 -10 to 2.7 x 10-9 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.
