Divacancy superstructures in thermoelectric calcium-doped sodium cobaltate

Divacancy superstructures in thermoelectric calcium-doped sodium cobaltate

We have grown single crystals of NaxCayCoO2 and determined their superstructures as a function of composition using neutron and x-ray diffraction. Inclusion of Ca2+ stabilizes a single superstructure across a wide range of temperatures and concentrations. The superstructure in the Na+ layers is base...
