TRANSPARENT CONDUCTING OXIDE SYNTHESIS OF ALUMINIUM DOPED ZINC OXIDES BY CHEMICAL COPRECIPITATION
Aluminium doped zinc oxides (AZO) are promising replacements for tin doped indium oxides (ITO) but thin films show a wide range of physical properties strongly dependent on deposition process conditions.

| description | Aluminium doped zinc oxides (AZO) are promising replacements for tin doped indium oxides (ITO) but thin films show a wide range of physical properties strongly dependent on deposition process conditions. Submicrometric 1% aluminum doped zinc oxide ceramics (AZO) are examined, prepared by coprecipitation, from Zn(NO3)2 and Al(NO3)3 aqueous solutions, sintered at 1200°C and subsequently annealed in 10-16 atm controlled oxygen fugacity atmospheres, at 1000°C. Electrical resistivity diminishes by two orders of magnitude after two hours of annealing and the Seebeck coefficient gradually changes from -140 to -50 µV/K within 8 h. It is concluded that increased mobility is dominant over the increased carrier density, induced by changes in metal-oxygen stoichiometry |
