Preparation and thermoelectric characteristics of flexible materials with oxide nanostructures
We have investigated the thermoelectric and crystallographic characteristics of ZnO nanostructures or reduced graphene-oxide formed on fabrics. By controlling the process parameters in a hydrothermal method, ZnO nanostructures grew on a cotton fabric [FIG.1]. The shape of ZnO nanostructure also could be changed by the parameters.

We have tried to fabricate n- and p-type semiconductor flexible materials by tuning the precursor. In adding Sb and Ag to ZnO nanostructures, these composites indicated negative and positive Seebeck coefficient, respectively [FIG.2].
