Low-Temperature Photothermal Measurements of High-TC Superconductors
Thermal conductivity provides important information on the scattering mechanisms in a material. In anisotropic materials, such as the high-temperature superconductors, the thermal conductivity depends on the anisotropy of both the charge carriers and the lattice contribution. The conductivity also depends intimately on the nature of the electron-phonon interactions which are a major source of the scattering. Since the electron-phonon interaction also plays a critical role in the Bardeen, Cooper, and Schrieffer (BCS) theory of superconductivity, measurements of the thermal conductivity can provide insight into the superconducting mechanism.
