Abstract

The effect of coupled substitution of Zr⁴⁺/Ga³⁺ for In³⁺ in In₂O₃ upon the structural, electrical and optical properties has been studied. The In_2-2xGa_xZr_xO₃ solid solution with bixbyite structure has been synthesized for 0 ≤ x < 0.15. A decrease in resistivity for the composition x = 0.025 (ρ_RT = 5.5x10^-3 Ω.cm) by approximately one order of magnitude if compared to In₂O₃ (ρ_RT = 2.2x10^-2 Ω.cm) was obtained. The maximum percent reflectance around 500 nm is lowered by 15% with respect to pure In₂O₃. These novel oxides show their potential as transparent conductors.
