Physics of High-Tc Superconductors highlights the important experiments that provide insights on the concept of high-temperature superconductors. Composed of 11 chapters, this book covers the theories and materials of these superconductors. The opening chapters of this book deal with the concepts at the cutting edge of materials science and the technical details of electron-phonon interaction calculations and their application to high-Tc superconductors. The subsequent chapters describe the various features of the atomic and electronic structure of high-Tc superconductor materials, such as quaternary, metallic, and pseudoperovskite copper oxides. These topics are followed by descriptions of the isotope effect, lattice vibrations, and optical spectra of high-Tc superconductor materials. The discussion then shifts to tunneling, relaxation, and morphological studies of these materials. The concluding chapter focuses on the superconductivity potential of bismates and thallates. Undergraduate materials science students will find this book invaluable.
