Book Description
Low-energy ion scattering is a powerful surface analysis technique for interrogating the structural and chemical makeup of a surface, as well as the electronic structure. We used this technique to probe the local electrostatic potential of Bi [subscript 2] Sr [subscript 2] CaCu [subscript 2] O [subscript 8], and corroborated the findings of density functional theory. Sputtering with Ar [subscript +] ions was conducted on this same material, revealing the formation of a Bi capping layer that prevents further damage due to the low surface energy of Bi. Finally, scattering was used to investigate atom-surface charge exchange at the Si(111) surface as a function of doping, a fundamental study which revealed that the bulk band gap has a strong effect on the neutralization of scattered ions, despite the work function being unchanged with added dopants.

Book Description
Unconventional superconductivity (or superconductivity with a nontrivial Cooper pairing) is believed to exist in many heavy-fermion materials as well as in high temperature superconductors, and is a subject of great theoretical and experimental interest. The remarkable progress achieved in this field has not been reflected in published monographs and textbooks, and there is a gap between current research and the standard education of solid state physicists in the theory of superconductivity. This book is intended to meet this information need and includes the authors' original results.
