Influence of a Strong Electric Field on the Electrical, Transport and Diffusion Properties of Carbon Nanostructures with Point Defects Structure

ABSTRACTDiffusion mechanisms and point defects in GaAs and related III-V compounds are discussed. An understanding of the As sublattice situation has been arrived at fairly recently and is presently tentative. Understanding of the Ga sublattice situation has become more acceptable in that experimental results are consistently explained by the Fermi-level effect and the As4 pressure effect. On the Ga sublattice, though controversies still exist, some are readily resolved by noting the role of the electric field produced by semiconductor electrical junctions, physical junctions, and surfaces.

And Diffusion

A simplified model is considered to describe the resistive transport and diffusion of charge carriers within or around an ER active particle under influence of AC electric field and temperature. The effective polarization strength, dielectric constant and dielectric loss of the particle are derived from this model. Considered the effects of shear field, the criteria for ER activity are presented as ωτ >10-4, 1<d/λ<102 and ωτ d/λ<1 for ω<103s-1. The criteria determine the lower and upper limits of the polarization rate and dielectric loss of ER particles. The criteria are testified by the following experimental results. First, the measured lower limit of diatomite particle conductivity is 7.3×10-8S/m. Second, the shear stresses at the shear rates from 9.9 to 100 s -1 at 1kV/mm field start to rise with temperature from 25°C. Third, with decreasing shear rate or/and increasing electric field strength, the peaks of shear stress shift down the lower temperatures.
