Uniaxial Pressure Study of Charge Density Waves in a High-T Cuprate Superconductor

This book presents comprehensive studies of charge density waves (CDW) in a high-Tc cuprate superconductor using x-ray scattering techniques under uniaxial pressure. Specifically, the work addresses inelastic x-ray scattering studies under uniaxial pressure performed on the underdoped cuprate YBa2Cu3O6.67(p=0.12, Tc=65K) with incoming photon energy in the resonant (E=931.3 eV, Cu-L3 edge) and non-resonant conditions (E=17.794 keV). This is a completely new approach to the investigation of charge density waves. It revealed new features of charge density waves in cuprates, whose properties had previously been inaccessible..

Hun-ho Kim gathered his first research experience studying ferroelectric domains using piezoresponse force microscopy at Seoul National University, Korea. He went on to perform a master study at the University of Stuttgart with a thesis prepared at the Max Planck Institute for Solid State Research, where he remained for his Ph.D. work His project was a new, challenging , and ultimately successful approach to understanding the complicated physics of cuprates.
