    The electric and electrostatic properties of polymers with negligible intrinsic charge carrier concentration are determined by the ratio of injection of excess charge carriers, e.g. from a metal electrode, to the rate of charge transport. Both, injection and transport of charge carriers are affected by polymer specific interface parameters, e.g. energy level of the polymer band gap states, barrier... View full abstract»

    We introduce a new experimental technique for directly measuring the energy and momentum scattering rates of hot electrons in dielectrics. Their energy distribution and impact ionization rate at a given electrical field F is a function of begin{equation*}F^{2} int^{E}_{0} gamma_{p}(E)gamma^{L0}_mu{ }(E)dEend{equation*} where ¿¿ is the momentum scattering rate and ¿Lo¿ the longitudinal optical ...

    The molecular nature of most insulating solids of practical importance is emphasized. As a consequence of weak molecular interactions, charge transport through such materials occurs by tunnelling between localized molecular electron states. The energies of these states are modified by local polarization and this is particularly important at a metal electrode - molecular solid interface where charg... View full abstract»

    It is shown that the relatively large concentration of impurities in cables is even higher in water trees. Gas bubbles observed in cavities filled with different salt solutions generate very high pressures able to fracture XLPE samples. It was also observed that fracture in XLPE under a cyclic mechanical load is frequency-dependent. The influence of oxidation on dielectric properties is also discu... View full abstract»

    Unlike apparent charge, energy is an inherent characteristic of partial discharge (DP) and may be used as an objective criterion for their evaluation. Since energy dissipation is responsible for the damaging effect of discharges, the amount of energy liberated in a PD situation is a suitable estimation of the involved risks. Discharge energy measurement was accomplished using a special and readily... View full abstract»

    A physical justification for the use of Weibull statistics in the assessment of dieelctric breakdown is presented in terms of a theoretical model of structural fluctuations in non-crystalline materials which has previously been applied to relaxation dynamics in such materials. A number of breakdown mechanisms have been considered and the relationship of the Weibull parameter to experimentally meas... View full abstract»

    Starting from the assumption that ¿¿conditioning¿¿ is necessary to trigger a breakdown and that its duration can be seen as the delay time before breakdown, a new approach to the problem of the dielectric stress of solid insulators is proposed. It is founded on the relationship existing between the delay time which is determined statistically, and the amplitude of the electrical field. The experim... View full abstract»

    SiO2 layers with low defect densities have been grown in a double-walled oxidation tube, for use as thin gate dielectrics in MOS IC's. Under all high-field stress conditions positively charged slow states are created at the Si-SiO2 interface. These can be neutralized by applying positive fields at the gate of an MOS device. Negative charge can also be generated, especially during a positive field ... View full abstract»

    Comparison is made between biopolymers, particularly proteins, and other organic polymeric materials which exhibit low levels of conductivity. Electron and hole transport in the latter is generally agreed to proceed by tunnelling processes between localized states. Similar ¿hopping¿ processes are invoked for proteins and the roles of polypeptide back-bone, and the aperiodic array of the residues... View full abstract»

    A surface of chlorophyll-a is deposited in the interelectrode space of an interdigital comb-shapedelectrode system. The conduction current under direct voltage and dielectric losses under a low frequency alternating voltage were then measured. The conductance values appeared to agree with and depend upon the light intensity on the specimen surface and upon ambient gas nature in which the specimen ... View full abstract»
