Influence of superstructures on rich transport properties of lithium cobaltate
In the vicinity of x ~ 0.75, LixCoO2 has potential as a thermoelectric, since it has a high Seebeck coefficient and metallic conductivity. We have performed the first successful... -
Superstructures in insulating and metallic lanthanum-doped sodium cobaltate
The thermoelectric properties of NaxCoO2 can be substantially improved by replacing Na ions by cations of higher valence. Our neutron diffraction studies on SXD for doping with...
