The IGZO solution (0.125 M) was prepared by dissolving indium nitrate hydrate (In(NO3)3 • xH2O), gallium nitrate hydrate (Ga(NO3)3 • xH2O) and zinc nitrate hydrate (Zn(NO3)2 • xH2O) powders (Sigma Aldrich) in 2-methoxyethanol (2-ME) as a solvent (anhydrous, Sigma Aldrich). The Al2O3 solution (0.8 M) was also prepared by dissolving aluminum nitrate nonahydrate (Al(NO3)3 • 9H2O) (Sigma Aldrich) powder in 2-ME as a solvent (anhydrous, Sigma Aldrich). The molar concentration of the Al2O3 solution used to construct flexible IGZO-TFTs was optimized to 0.15 M, which enables the device to operate at 1 V. The IGZO and Al2O3 solutions were magnetically stirred at 70 °C for 12 h at an ambient atmosphere.

The IGZO precursor solutions were prepared by mixing zinc nitrate hydrate, indium nitrate(III) hydrate, and gallium nitrate(III) hydrate in 2-methoxyethanol and all materials associated with IGZO were purchased from Sigma Aldrich Co. The total concentration of the solution was 0.12 M and the molar ratio was adjusted to 6.5(In): 1.5(Ga): 2(Zn). This solution was vigorously stirred (600 rpm) over 12 h. Meanwhile, a heavily p-type doped silicon wafer covered with 300 nm thick, thermally grown SiO2 was sonicated in acetone and isopropyl alcohol for 5 min. In order to remove the residual solvent on the wafer, N2 gas was blown onto the wafer using a blower system. The substrates were treated with ultraviolet-ozone for 5 min. To produce the high viscosity inks used in the screen-printing process, ethyl cellulose (Sigma Aldrich Co.) was added to commercial Ag ink (Silverjet DGP, ANP Co.) at a weight fraction of 1%. The ink was stirred and heated to a temperature of 75 °C for 2 h to reduce the solvent content and increase the Ag particle weight percent.
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.
