Abstract
The thermopower and the electrical resistivity of [BiCaO/sub 2/]/sub 2/[CoO/sub 2/]/sub 1.69/ and corresponding iodine intercalated single crystals have been measured. Upon intercalation, the thermopower is drastically decreased, indicating that there is a hole doping by charge transfer from the intercalated iodine layer to the hexagonal CoO/sub 2/ layer. The resistivity is increased due to stacking faults and disordered structures. Structural analyses confirmed the stacking scheme along the c direction, with the localisation of iodine between the [BiO] double layers. The effect of intercalation on the thermoelectric properties suggested discussions from the view point of hole doping and nano-block layer coupling effect.
