Introduction -- Angle-Resolved Photoemission Spectroscopy -- Growth of Bi2Sr2Ca1−xDyxCu2O8+δ Single Crystals -- Nodal Electron Coupling in the Bi2Sr2Ca1Cu2O8+δ -- High Energy Dispersion in Bi2Sr2Ca1Cu2O8+δ -- Normal Electron Self-Energy and Pairing Self-Energy in Bi2Sr2CaCu2O8 -- Superconducting Gap and Pseudogap in Bi2Sr2CaCu2O8+δ -- Summary.
This book mainly focuses on the study of the high-temperature superconductor Bi2Sr2CaCu2O8 by vacuum, ultra-violet, laser-based, angle-resolved photoemission spectroscopy (ARPES). A new form of electron coupling has been identified in Bi2212, which occurs in the superconducting state. For the first time, the Bogoliubov quasiparticle dispersion with a clear band back-bending has been observed with two peaks in the momentum distribution curve in the superconducting state at a low temperature. Readers will find useful information about the technique of angle-resolved photoemission and the study of high-temperature superconductors using this technique. Dr. Wentao Zhang received his PhD from the Institute of Physics at the Chinese Academy of Sciences.
