INVESTIGATION OF ELECTRIC CHARGES CARRIED BY MOVING DISLOCATIONS IN NaCl SINGLE CRYSTALS
نویسندگان
چکیده
The charge carried by moving dislocations was measured in NaCl single crystals doped with divalent cation impurities, and the connection between the charge and the concentration of the free cation vacancies of the crystal was investigated. According to the experimental results the dislocations carry negative charge and the magnitude of the charge changes proportionally to the concentration of the free cation vacancies independently of the way (divalent cation doping, heat treatment, change of the measuring temperature) the vacancy concentration was changed.

Quasi-Static Theory for Uniaxial Chiral Omega Media
The problem of unbounded uniaxial chiral omega media in the presence of both static electric and magnetic point charges is investigated. For this purpose scalar electric and magnetic potentials in these media are introduced. Using these potentials, the corresponding electric and magnetic fields are determined. The similar problem of static electric and magnetic current sources with the goal of ...

In this paper, the localized TM surface waves of a nonlinear self-focusingleft-handed slab sandwiched between a uniform medium and a one-dimensionalphotonic crystal (1D PC) is analytically investigated. Our method is based on the firstintegral of the nonlinear Maxwell's equations. For the TM surface waves, the presenceof two electric field components makes the analysis difficult. Therefore, we ...

متن کاملEffects of Plastic Deformation on Ionic Conductivity
The principal effects of plastic deformation on the low-temperature conductivity of alkali halide crystals are summarised and interpreted as follows : 1. The high conductivity during deformation is due to the movement of charged dislocations under the forces exerted simultaneously by the stress and the applied electric field. 2. The increased conductivity following deformation which subsequentl...
