Influence of pulsed laser deposition growth conditions on the   thermoelectric properties of Ca3Co4O9 thin films
  Thin films of the misfit cobaltite Ca3Co4O9 were grown on (0001)-oriented (c-cut) sapphire substrates, using the pulsed-laser deposition techniques. The dependence of the thermoelectric/transport properties on the film growth conditions was investigated
