      the main factors influencing the different solubility limits of al- and ga-doped zno systems are studied. the different thermoelectric properties of al- and ga-doped zno systems were attributed in prior studies to the different solubility limits and secondary phases of these systems. in this study, the origin of these differences, i.e., the ga2o3(zno)9 secondary phase, was suppressed by a low-temperature synthesis process for the zn0.98ga0.02o solid solution. as a result, a novel synthesis process for zn0.98ga0.02o solid solution without the ga2o3(zno)9 phase was established, and the thermoelectric properties with and without the ga2o3(zno)9 secondary phase were compared. the thermoelectric properties of zn0.98al0.02o and zn0.98ga0.02o specimens without al2o3(zno)9/ga2o3(zno)9 phases were also compared.
