What kinda experiments prodive evidence that SC resides in the CuO layers? Off hand I can't think of how any experiments that I'm familiar with could distinguish if the CuO or another plane where SC. Thanks

ZapperZ said:2. ARPES measurements see the opening of the anisotropic superconducting gap consistent with where the band crosses the Fermi surface on the CuO plane. Furthermore, we see the split-bands effects from the bonding-antibonding bands in high-Tc compounds with a dual-layer CuO planes per unit cell.

nbo10 said:Thanks for the response ZapperZ. Is ARPES a bulk measurement? Do you have any quick reference on ARPES? If not I can do a literature serach.
ZapperZ, would you mind if I PM a few questions that are HTSC related? Thanks

The pseudogap in high-temperature superconductors: an experimental survey, T. Timusk and B. Statt, Rep. Prog. Phys. 62, 61-122, (1999).
Superconductivity (SC) in CuO layers is the phenomenon of zero electrical resistance and perfect diamagnetism observed in layers of copper oxide. It is important because it has potential applications in various industries such as energy transmission, medical imaging, and transportation.
Evidence for SC in CuO layers includes the observation of zero electrical resistance, perfect diamagnetism, and the Meissner effect (expulsion of magnetic fields) at low temperatures. This is supported by experimental data from various techniques such as resistivity measurements and magnetic susceptibility measurements.
Experiments conducted to study SC in CuO layers include resistivity measurements, magnetic susceptibility measurements, specific heat measurements, and tunneling spectroscopy. These experiments have provided valuable information about the behavior and properties of SC in CuO layers.
One of the main challenges in studying SC in CuO layers is the complexity of the materials, as well as the difficulty in controlling and manipulating their properties. Additionally, the high temperatures required for SC in CuO layers make it challenging to conduct experiments and obtain reliable results.
SC in CuO layers has potential applications in energy transmission, medical imaging, and transportation. It can also be used in various high-tech devices such as superconducting quantum interference devices (SQUIDs) and superconducting magnets for research purposes.
