In this research, we investigate the memory behavior of poly(3,4 ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) cross bar structure memory cells. We demonstrate that Al/PEDOT:PSS/Al cells fabricated elements exhibit a bipolar switching and reproducible behavior via current–voltage, endurance, and retention time tests. We ascribe the physical origin of the bipolar switching to the change of the electrical conductivity of PEDOT:PSS due to electrical field induced dipolar reorientation.

Ferrocene is a well-known electron donor due to its chemical stability and redox behaviour. By introducing azo dye as an acceptor in the system, the characteristics of azo-ferrocene (AF) compound as a semiconductor material have been investigated. A single layer film of AF compound was deposited on an indium tin oxide (ITO) glass substrate by electrochemical method in the potential range of 0.4 V to 0.8 V. Electrical conductivity of the thin film was investigated using a four-point probe and I-V characteristic of the diode was determined via a two-point probe method. AF material showed an average electrical conductivity of 0.246 ± 0.003 Scm-1. The forward current-voltage measurement demonstrated a bias voltage in the range of 0.87 V to 10.0 V, and the backward current-voltage measurement indicated a bias voltage in the range of-0.87 V to-7.0 V. In both forward and backward voltages, the current showed a slow increase beyond the readings of 10.0 V to-7.0 V.

The paper presents a generalized analysis of literature data on the current-voltage, omics characteristics and electrical conductivity of membrane systems. Based on an analysis of the literature, it is noted that electrodialysis is a promising method for the separation of solutions for the production of ammonium nitrate. An analysis of literature revealed that the application of an external constant electric field to the membrane separation of solutions containing charge-transporting components (nitrate ions and ammonium ions) causes the directed transfer of cations and anions through the membranes. The studies revealed that with the baromembrane separation of the studied solutions with increasing transmembrane pressure, the specific output stream increases. This is due to an increase in the driving force of the process. For the OFAM-K anode membrane, with an increase in the current density, with the electrobaromembrane separation of the ammonium nitrate solution, the specific output stream decreases, which is associated with a change in the pH value of the acidified anode permeate. nd for the OPMN-P cathode membrane, the specific output stream increases with a change in the pH of the alkalized cathode permeate. A modified mathematical equation is proposed for theoretical calculation of the specific output stream and the retention coefficient of the OFAM-K and OPMN-P nanofiltration membranes. Experimental studies of membrane systems equipped with the anode OFAM-K and the near-cathode OPMN-P membranes from voltage and transmembrane pressure revealed that for the aqueous solution of ammonium nitrate there are two characteristic periods on the current-voltage, omics characteristics and electrical conductivity of the membrane system (the first period is beyond regime, dissociation of water (H+ and OH-) at the phase boundary with the advent of additional electric current carriers, the second is the degradation of the active layer of a semipermeable membrane). When studying the current-voltage characteristics of a membrane system equipped with an anode OFAM-K and a near-cathode OPMN-P membranes, when separating model and technological solutions, a decrease in the total omics resistance of the system is observed, which is associated with the solution throttling process.

Concrete is a key support material of underground chamber, its stress state is important parameter that can characterize the stability of underground chambers. The changing rule of the electrical conductivity of C50 steel fiber concrete in relation to the changes of the current, voltage and pressure was studied experimentally. And resistivity-stress regression equations of the concrete was fitted with much high correlation coefficient. Research results show that: (1) within the framework of elastic deformation, the electrical conductivity of concrete increases with the strengthening pressure (i.e., the concrete resistivity decreases with increasing pressure); (2) there exists the good correlation between the resistivity and pressure of the concrete; (3) given the certain pressure, the conductivity of the concrete is to some extent unaffected by voltage and current.

We investigated current-voltage (I-V) characteristics of bulk polyaniline and aniline polymerized inside nanopores of chromium terephthalate dielectric matrix MIL-101. The temperature dependence of electrical conductivity σ (T) of these materials are described by the fluctuation-induced tunneling model (FIT), which means that the main contribution to a net conductivity is caused by contacts between particles of the polyaniline. The comparison of I-V for these two types of materials shown that I-V characteristics of bulk polyaniline are described by the quasi-1D VRH model while for aniline polymerized inside nanopores of chromium terephthalate dielectric matrix MIL-101 by extended FIT model.
