Mechanism of d-plane in Cuprate Superconductivity

Abstract

The basic structure of cuprates consists of 𝐶𝑢𝑂2 layers. These cooper oxide materials are responding to physics of superconductivity. The 𝑑𝑥2−𝑦 2 orbital state of the 𝐶𝑢2+ ions, suggest that electron-electron interactions are more significant than electron-phonon interactions in cuprates making the superconductivity unconventional. And also the d-wave pairing state is dominant in the cuprate. In this thesis we explain that 𝑑𝑥2−𝑦 2play important role in high temperature superconductivity.
