摘要: ABSTRACT: Dielectric and electrical properties of a benzotriazole fluorene copolymer were investigated using current-voltage(I–V), capacitance-voltage (C–V), conductance–voltage (G/w–V) measurements at room temperature. The parameters,barrier height (u Bo ), ideality factor (n) obtained from the forward bias LnI-V plot found as 0.453 eV 2.08, respectively.The R s values 2.20, 2.12, 1.90 X dV/dLnI versus I, H(I) I F(V)-V plots, respectively. dielectricconstant (e 0 dielectric loss 00 ac conductivity ( r ) are strong function voltage frequency. Decreasein e with increasing frequency was observed. On other hand, increase wasobserved .Experimental results show that conjugated plays an important role in barrier height, idealityfactor, series resistance, parameters.
