    Dielectric spectroscopy investigation of hybrid conjugated polymeric memristors

  • Original language description

    A new device has been recently realized, though it was postulated years ago as one of the fundamental passive circuit elements. This new device alters its conductivity on its electronic history and is referred to as a memory resistor or &quot;memristor&quot;. The growing interest in memristors has resulted in the development of several concepts for the use of these devices, such as utilizing memristive systems for reconfigurable logic circuits, or new computer memory concepts. Conjugated polymers as two-terminal memory devices have been recently reviewed and the majority of the devices presented focused on developing materials appropriate for dynamic random-access memory (DRAM), static random-access memory (SRAM), or write once read many (WORM) applications where a bistable conductivity switching response is an appropriate. A newly synthesized hybrid conjugated polymer with pendant carbazole rings, that is, poly(4-(6-(9H-carbazol-9-y)hegyl)-4H-dithieno[3,2-b:20,30-d]pyrrole) (pC6DTP), was employed in the fabrication of a two-terminal memristor with a Al/pC6DTP/ITO configuration where the polymer was electrochemically doped. In the present work we focused on the information provided by thermally stimulated depolarization currents (TSDC) on the molecular mobility in condensed matter. The cyclic voltage-pulse train response of a pC6DTPox-based device to a number of linear-increasing or decreasing voltage pulses was studied in order to assess the ability of the device to track its voltage history through resistivity modulations. The results of measurements prove the memristic behaviour by ability to module the electrical resistivity of device by applied voltage.
