Bombardment Induced Transport of Rb⁺ through a K⁺ Conducting Glass vs. K⁺ Transport through a Rb⁺ Conducting Glass

Abstract

Abstract:The transport of rubidium ions and potassium ions respectively through rubidium and potassium ion conducting glasses has been investigated by means of the recently developed low energy bombardment induced ion transport (BIIT) approach. Here, the combination of a bombarder ion M 1 (Rb + ,K + ) and a charge latter corresponds to the transport of rubidium ions through a potassium ion conductor and vice versa. The native ion BIIT yields the intrinsic ionic conductivities and activation energies for ion hopping in line with impedance spectroscopic data also presented. The foreign ion BIIT leads to the generation of diffusion profiles up to 100 nm into the glass sample as revealed by time-of-flight secondary ion mass spectrometry (ToF-SIMS). The analysis of such depth profiles by means of Nernst-Planck-Poisson theory provides access to the concentration dependence of the diffusion coefficients. The concentration dependence of the potassium ion diffusion coefficient, (K + ), is markedly different for the rubidium glass vs. the potassium glass matrix. Within the error bars the concentration dependence of the rubidium ion diffusion coefficient, (Rb + ), is negligible in both glasses.

“…From the publication, it cannot be excluded that their values reported results from a pressed powder sample leaving the question whether identical conductivities are to be expected at all. CAIT experiments have previously been tested in comparison to the DC limit of impedance spectroscopy as an established technique, and within the error margins, identical results were obtained. ,, …”

Self-organizing layers from complex molecular anions

“…Neutralization of cations occurs at higher coverages where electron transfer through the insulating layer becomes possible due to buildup of a potential on the surface 35 . Surface potentials also have been shown to drive ion transfer in certain materials 37 , 38 . In contrast, our recent studies of stable polyoxometalate Keggin anions, PM 12 O 40 3− (M=Mo, W), pointed strongly to preservation of their negative charges after deposition 39 , 40 .…”

“…This setup is similar to that described in Ref. [120], with the exception that the mask was in contact with the sample in that work. Since the PMO is a good electrical conductor [122,123] for negative charge carriers (electrons and possibly O 2− ions), the ions were neutralized upon adsorption at its surface.…”

“…The basic concept of the experimental approach has been described in previous reports [114,119,120]. Only a brief summary of the important key features is given in this section.…”
