Study of phase evolution and dielectric properties of Sr2Mn0.7Sn0.3O4 [PDF]

open access: yesProcessing and Application of Ceramics, 2023
Ruddlesden-Popper oxide Sr2Mn0.7Sn0.3O4 was synthesized by solid state method by calcining at different temperatures between 1200 and 1500°C. The phase evolution during thermal treatments was investigated and it was shown that the powder calcined at 1500°

Contribution of Surface Distributions to Constant-Phase-Element (CPE) Behavior: 1. Influence of Roughness [PDF]

open access: yesElectrochimica Acta, 2015
Abstract Finite–element simulations were used to calculate the influence of surface roughness of V-shaped grooves on the impedance of ideally polarized disk electrodes. The characteristic length associated with roughness was found to depend on the width or period of the roughness as well as the roughness factor.

Constant-Phase-Element Behavior Caused by Coupled Resistivity and Permittivity Distributions in Films [PDF]

open access: yes, 2011
A recent proposed model showed that the impedance of a film with a uniform permittivity and a resistivity that varies along its thickness according to a power-law is in the form of a constant phase element (CPE). This model is further considered in order
