Abstract:
The basic structure of cuprates consists of 𝐶𝑢𝑂2 layers. These cooper
oxide materials are responding to physics of superconductivity. The 𝑑𝑥2โ𝑦 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 𝑑𝑥2โ𝑦 2play important
role in high temperature superconductivity.
