| Popis: | The electrical properties investigation for poly Vinyl Alcohol (PVA) doped with Alizarin orang Azo dyfilms was carried out for films prepared by cast method. Conduction processes were analysed througmeasuring (Current – Voltage) and (Conductivity – temperature) relationships in the voltage and temperatureranges (1-250) V and (293 -333) K respectively. The resistance of the doped films is found to have negative thermal coefficient.The activation energy at temperature (293-333)K was about (0.74)eVis found from the ohmic region of the dark (current – voltage) characteristic. The conductivity at temperature293 K was equal to 1.2×10 -10 (S.cm -1 ).The deviation from ohm's law has beeanalysed in term of the available conduction theories, Schotky conduction mechanism was concluded. |
