Preparation and transport properties of non-hydrated Na0.5CoO2 single crystals

Single crystals of Na0.5CoO2 were obtained through a flux method followed by deintercalation of sodium. The Na0.5CoO2 samples were found to be vulnerable to water in the air and a hydration process in which H2O molecules fill oxygen vacancies in CoO2 layers is suggested to be responsible for the unusual vulnerability to water. The transport properties, including resistivity (ρ), thermopower (S ...
