Abstract

The local structure of In₂O₃ cosubstituted with Zn and Sn (In_2-2xSn_xZn_xO₃, x≤0.4 or ZITO) was determined by extended X-ray absorption fine structure (EXAFS) for x=0.1, 0.2, 0.3 and 0.4. The host bixbyite In₂O₃ structure is maintained up to the enhanced substitution limit (x=0.4). The EXAFS spectra are consistent with random substitution of In by the smaller Zn and Sn cations, a result that is consistent with the "good-to-excellent" conductivities reported for ZITO.
