The IGZO solution was composed of indium nitrate hydrate (In(NO3)2·xH2O, Sigma Aldrich), gallium nitrate hydrate (Ga(NO3)2·xH2O, Sigma Aldrich, St. Louis, MO, USA), and zinc nitrate hexahydrate (Zn(NO3)2·6H2O, Sigma Aldrich) with a molar ratio of 6:1:2, dissolved in ethylene glycol monomethyl ether (Daejung, Siheung, Republic of Korea). The IZO solution was synthesized by blending In(NO3)2·xH2O and Zn(NO3)2·6H2O with ethylene glycol monomethyl ether (Daejung). For the division of ratios, IZO solutions were prepared by mixing the In precursor solution and Zn precursor solution in proportions of 8:2, 5:5, and 2:8. These processes resulted in a 0.1 M solution of IGZO and a 0.1 M solution of IZO. After stirring, they were stored in a humidity desiccator for more than a day before usage.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
