The local structure of In{sub 2}O{sub 3} cosubstituted with Zn and Sn (In{sub 2-2x}Sn{sub x}Zn{sub x}O{sub 3}, x {le} 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 In{sub 2}O{sub 3} 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.
