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.Generally, there are two types of cuprate superconductors according to the charge of conducting carriers (holes or ... for one-layer, two-layer and three-layer Cu-O in a single cell, their highest transition temperatures are aˆ¼34 K, aˆ¼96 K ... A typical phase diagram of cuprate high-temperature superconductor is shown in Fig.
