“…This means that the conductivity of BPACC sample in region I depends mainly on the type of free carriers present in the sample. These carriers can be obtained by breaking weakly bonded ions inside the skeleton of BPACC sample or the electrons injected from the electrodes [11,20,23]. This agrees with what we assumed earlier, at 300 and 330 K, the conduction mechanism depends on the free carriers within the BPACC sample.…”

Transient current (I-t), current-voltage (I-V) characteristics, and dc conductivity ln(σ) for bisphenol A corncobs (BPACC) sample were investigated. At higher temperatures, I-V characteristics reveal that the dc current for the sample undergoes two regions one due to ohmic conduction and the other has been attributed to Space charge limited current (SCLC). The activation energy (E a ), the electron mobility (μ o ), effective electron mobility (μ e ), the concentration of the charge's concentrations in conduction band, trapping factor (θ) and the trap concentration (N t ) were calculated. At lower temperatures, the dc current exhibits a peculiar behavior for I-t regime and I-V characteristics. Transient current of BPACC sample exhibits approximately constant value at constant electric field and it has saturation value for I-V characteristics. The attained results suggest strongly the applicability of this material in the electrical applications.
