ABSTRACT

Transient current (I-t), current-voltage (I-V) characteristics, and dc conductivity ln(σ) for bisphenol A corn-cobs (BPACC) sample were investigated. At higher temperatures, I-V characteristics reveal that the dc cur-rent 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 (Ea), the electron mobility μo), effective electron mobility ?μe), the concentration of the charge’s concentrations in conduction band, trapping factor (θ) and the trap concentration (Nt) 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.
