A Geometry-Induced Finite Warburg element for Reversible Diffusion Impedance at Microdisk Electrodes
Kazuhiko Seki, Yuko Yokoyama, Masahiro Yamamoto
A compact analytical representation is developed for the diffusion impedance of a disk electrode under reversible conditions, obtained by transforming the chronoamperometric relaxa…
Integral-equation analysis of transient diffusion-limited currents at disk electrodes: Asymptotic expansion and compact approximation
Kazuhiko Seki, Yuko Yokoyama, Masahiro Yamamoto
The transient diffusion-limited current at a disk electrode following a change in interfacial ion concentration induced by a potential step is analyzed with direct relevance to chr…
Temperature-Gradient Effects on Electric Double Layer Screening in Electrolytes
Kazuhiko Seki
Temperature gradients drive asymmetric ion distributions via thermodiffusion (the Soret effect), leading to deviations from the classical Debye--Hückel potential.We introduce the E…
Photoluminescence decay of mobile carriers influenced by imperfect quenching at particle surfaces with subdiffusive spread
Ryuzi Katoh, Kazuhiko Seki
We recently presented a quantitative model to explain the particle-size dependence of photoluminescence (PL) quantum yields and revealed that exciton quenching is not diffusion con…
Method of images for one-dimensional discrete random walk under a reflecting barrier
Kazuhiko Seki
The transition probability for a one-dimensional discrete symmetric random walk under a reflecting barrier was once given by the method of images. [S. Chandrasekhar, Rev. Mod. Phys…
