Structural and transport properties of epitaxial NaxCoO2 thin films Academic Article uri icon

abstract

  • We have studied structural and transport properties of epitaxial NaxCoO2 thin films on (0001) sapphire substrate prepared by topotaxially converting an epitaxial Co3O4 film to NaxCoO2 with annealing in Na vapor. The films are c-axis oriented and in-plane aligned with [1010]NaxCoO2 rotated by 30 from [1010] sapphire. Different Na vapor pressures during the annealing resulted in films with different Na concentrations, which showed distinct transport properties.
