Sol-gel chemistry is an approach to synthesize materials through a phase transformation from liquid precursors to a sol known as a colloidal suspension and finally to a gel which is a network structure.

However, it was not until the last decade that investigation on sol-gel metal oxides has been rapidly advancing. As depicted in Figures 3 a and 3 b , the metal cations undergo a hydrolysis reaction through the loss of a proton by the water molecules, leading to metal hydroxides. Subsequently, the condensation reaction occurs to form oxide M-O-M frameworks through an oxolation reaction between metal hydroxides Figure 3 c.

Sol-gel chemistry in metal oxide materials. Representative chemical reactions are shown for b hydrolysis and c condensation. According to previous investigation, the high temperature annealed oxide thin films were composed primarily of oxide M-O-M framework.

However, the low temperature annealed one contained large amounts of metal hydroxides M-OH. Unfortunately, the high-temperature annealing process is not compatible with the flexible substrates.

Thus, for the full realization of flexible and large-area oxide electronics, it is essential to develop low-temperature solution-processed techniques. Figure 4 shows the schematic diagram of low-temperature approaches for solution-processed oxide TFTs. In general, two main routes have been developed to lower the post-annealing temperature: 1 novel precursor approaches and 2 innovative post-treatment methods.

The first route includes alkoxide precursors, combustion chemistry, and aqueous precursors, etc. Table 1 and Figure 5 summarize the recent advances of low-temperature solution-processed n-type metal oxide TFTs.

Recent advances of low-temperature solution-processed n-type metal oxide TFTs 3. This approach demonstrates for the first time that solution-processed metal oxide TFTs with good device performance can be achieved at low processing temperature.

One of the drawbacks of the method is that the metal alkoxide precursors are unstable and require a complicated synthesis process.
