The charge carrier transport features of organic dielectric layers on the base of double hydrazone derivative and polycarbonate (PC) mixture of ratio 1:1 by weight have been investigated. The dielectric layers have been cast from solution of both organic materials on thin poly(ethylene theraphthalate) films coated by aluminum layer. Using dosed charging-discharging method, by measuring charge-voltage (C-V) characteristics, the dielectric features of organic polymer layers have been investigated. Latter characteristics enabled to evaluate layer's dielectric permittivity, surface resistance and it's dependence on electric field and polarity of charging potential. Investigation of the hole drift mobility dependencies on electric field by time-of-flight method demonstrated that the hole mobility increased from 3.5∙10-7 cm2/Vs till 2∙10-6cm2/Vs with the electric field increasing from 1.6∙105 V/cm up to 6∙105 V/cm.
