Abstract
The layered oxide, NaxCoO2 shows a variety of behaviors that make it the subject of much current debate. These include a complex phase diagram as a function of x. This phase diagram has compositions with magnetism, metal insulator transitions, and most remarkably, exceedingly high thermopower combined with high metallic conductivity. Furthermore, upon hydration, the material becomes a superconductor whose nature is not yet well understood. The purpose of this talk is to introduce this compound and its properties using the electronic structure as a basis. Some properties, such as the thermopower, and magneto-thermopower, appear to be understandable at the level of standard electronic structure theory, while others remain mysterious. Some related oxides that may have properties similar to NaxCoO2 are discussed.
Series This talk is part of the Quantum Matter Seminar series.
