Abstract

The phase evolution and electrical characteristics of ln₂O ₃(ZnO)₃ were examined when (Zn_0.5Sn _0.5)_1.5 (Zn:Sn = 1:1 ratio) was substituted for InO _1.5 in ln₂O₃(ZnO)₃. As the amount of (Zn_0.5Sn_0.5)_1.5 substitution increased up to 8 at%, a single phase of ln₂O₃(ZnO)₃ was maintained with a homogeneous grain size distribution, constant electrical characteristics and decreasing lattice constants. When the amount of (Zn _0.5Sn_0.5)_1.5 is increased over the solubility limit (about 8 at%), the second phases of ln₂O₃(ZnO) ₄ and Zn₂SnO₄ appeared and the volume fraction of the ln₂O₃(ZnO)₃ matrix decreased, while lattice constants remained unchanged. When 16 at% of (Zn_0.5Sn _0.5)_1.5 was substituted, the ln₂O ₃(ZnO)₃ phase disappeared and three phases of ln ₂O₃(ZnO)₄, Zn₂SnO₄ and unreacted ln₂O₃coexisted. Because of the precipitation of the second phases, grain size decreased greatly. Carrier mobility and electrical conductivity were also decreased due to the disappearance of the ln ₂O₃(ZnO)₃ phase and the decrease of grain size.
