Superconducting materials: the w story
arXiv:1908.04419 · doi:10.1007/s10948-019-05284-5
Abstract
Ted Geballe has contributed enormously to the knowledge of superconducting materials during an illustrious scientific career spanning seven decades, encompassing groundbreaking discoveries and studies of both so-called conventional and unconventional superconductors. On the year of his 100th birthday I would like to argue that all superconducting materials that Ted investigated, as well as those he did not, have one thing in common that is not generally recognized: hole carriers. This includes doped with , for which Ted has proposed that superconductivity is driven by negative-U pairing. I will discuss why hole carriers are necessary for a material to be a superconductor, and the implications of this for the understanding of the fundamental physics of superconductivity.
To be published in Ted@100 Festschrift, a special issue of JSNM in honor of Ted Geballe's 100th birthday
