Abstract

In this work, we analyse the effect of electron density fluctuations of in layered superconductors on the transition temperature T-c. Primarily, we consider the effect of thickness of conducting layer in modelling of superconducting compounds. It is observed that increasing the thickness of conducting layers increases the transition temperature Tc. Also it is shown that, the fluctuations of electron density has negligible character in the case layers with highly different dielectric constants. Obtained results are applicable to Bi(2)Sr(2)Ca(n-1)CunO(2n+4+)delta compounds with n = 1,2,3. Published by Elsevier B.V.
