Abstract: Zn1-(x+y)GaxInyO (x+y=0.005, 0.007 and 0.009) compounds which consist of single phase of hexagonal ZnO were prepared using solid state reaction method. To develop the design paradigm for fabrication of high quality thermoelectric ZnO based materials, the relationship between the average ionic radius of dopants in Zn site of samples and ZT values was examined. The experimental results indicated that the ZT value was improved by using concept of average ionic radius of dopants for development of high quality thermoelectric ZnO based materials.
