This allowed us to easy fabricate large targets with high density suitable for sputtering TCO films. Without using any cold or hot pressing techniques, The ITZO ceramic reaches a high bulk density (~ 92 % of InR2ROR3R theoretical density). XRD diagrams show a high solubility limit for Sn and Zn when they are co-doped into InR2ROR3R forming a solid-solution. They confirm a bixbyte structure typical for InR2ROR3R with no extra peaks that could correspond to Sn and/or Zn based oxides. A very low electrical resistivity is obtained, for [InR2ROR3R:SnR0.10R]:ZnR0.10R (1.7×10P -3 P Ω.cm, lower than ITO counterpart), due to high carrier mobility. This high mobility is correlated to the strong enhancement of the grain percolation as shown by SEM micrographs
