Synthesis, Electrical Properties and Na Migration CuP As

mechanism for its migration is via cation vacancies Another prominant irradiation defect is known as F center, an oxygen vacancy trapping two electrons The forma-tion energy of the cation vacancy and the F center in Li2O is calculated The e ect of relaxation and the in uence of defects on the electronic properties are investigated

Cation Migration and Coercivity in Mixed Copper Cobalt Spinel

the migration of Cu2‘ ions from the octahedral to the tetrahedral sites in the spinel lattice, as revealed by the variation of the tetragonal distortion (c/a) of the unit cell (Fig 3) as well as the saturation magnetization, M 4 (Fig 4) In the SC sample, the copper ions occupy the octahedral sites of the spinel lattice, leading to a

Size e ect in Quincke rotation: a numerical study

for the positive and the negative ions coupled with Navier-Stokes and Poisson equations Doing so, we compute the bulk charge distribution and the velocity field in the liquid surrounding the cylinder For sufficiently small cylinders, we show that the smaller the cylinder is, the smaller its angular velocity when submitted to a DC electric field

Effect of Cations on The Diffusivity of The Charge Carriers

counter-ions as chloride ions 4 Results and discussion Examples of experimental diagrams are shown in Figs 1–4 in Nyquist coordinates (i e the imaginary part as a function of the real part) Figs 1 and 2 corresponding to Na+ (pH 1 and 2) and Fig 3 corresponding to Zn2+ (pH 1) display qualitatively the same typical aspects of a large di•u-

Migration (déplacement des espèces chargées dans un champ électrique) Le passage du courant dans la solution est assuré par la migration des ions sous l’effet d’un champ électrique Les anions circulent dans le même sens que les électrons vers
