Özet
Dielectric and electrical properties of a benzotriazole and fluorene copolymer were investigated using current-voltage (I-V), capacitance-voltage (C-V), and conductance-voltage (G/w-V) measurements at room temperature. The electrical parameters, barrier height (?Bo), and ideality factor (n) obtained from the forward bias LnI-V plot were found as 0.453 eV and 2.08, respectively. The Rs values were found as 2.20, 2.12, 1.90 ? using dV/dLnI versus I, H(I) versus I and F(V)-V plots, respectively. The dielectric constant (??), the dielectric loss (??), and the ac electrical conductivity (?ac) are a strong function of voltage and frequency. Decrease in ?? and ?? values with increasing frequency was observed. On the other hand, the increase of ?ac with increasing frequency was observed. Experimental results show that the conjugated copolymer plays an important role in the values of barrier height, ideality factor, series resistance, and dielectric parameters. © 2012 Wiley Periodicals, Inc.
