A simple model to estimate the optimal doping of p - Type oxide superconductors

Abstract

Oxygen doping of superconductors is discussed. Doping high-T c superconductors with oxygen seems to be more efficient than other doping procedures. Using the assumption of double valence fluctuations, we present a simple model to estimate the optimal doping of p-type oxide superconductors. The experimental values of oxygen content for optimal doping of the most important p-type oxide superconductors can be accounted for adequately using this simple model. We expect that our simple model will encourage further experimental and theoretical researches in superconducting materials.

A Model to Study Microscopic Mechanisms in High-Tc Superconductors

“…However, the main objective of this chapter is to discuss the role of double valence fluctuations in p-type oxide superconductors. In a previous work (Luiz, 2008) we have suggested a simple phenomenological model useful to calculate the optimal doping of p-type high-T c oxide superconductors. In this chapter we study possible microscopic mechanisms in high-T c superconductors in order to give theoretical support for that simple model.…”
