Divacancy superstructures and enhanced thermopower in NaxCayCoO2
Replacing Na ions in NaxCoO2 with divalent Ca ions results in the formation of ordered arrays of divacancy clusters, rather than the trivacancy clusters found for the pure... -
Understanding enhanced thermoelectric properties of sodium cobaltate doped by...
The thermoelectric power factor for (Na1-y¿My¿)0.8CoO2 is dramatically increased when M = Sr, but it is essentally unchanged from the pure compound when M = Ca. Our previous SXD...
