Enhanced thermoelectric properties of NaxCoO2 whisker crystals

Journal Article


Abstract


  • An unconventional method to grow whisker single crystals of thermoelectric cobalt oxide was studied and their transport properties and chemical compositions were determined. The electrical resistivity and thermoelectric power of the whiskers were 102 ����cm and 83 ��V/K at 300K. The whisker formation mechanism was investigated by performing the thermogravimetric (TG) measurements. The results show that fast evaporation of potassium occurs during firing, which is essential for the growth of whiskers.
