Abstract
Solution-based metal oxides have been attracting a lot of attention due to the low cost, high throughput a nd simple chemical composition control when compared with vacuum-based systems. These materials have outst anding properties such as high optical transparency, chemical and thermal stability and mechanical toughness. A lso, facile tailoring of solution-based metal oxides leads to multifunctionality allowing their application in different a reas, like sensing, energy and flexible displays. Particularly for large-area electronics the exploration of a crucial co mponent, the thin film transistor (TFT) and their key materials components, the semiconductor, the dielectric, the conductor as well as substrate are demanded. To boost the implementation of TFTs emerging printing techniques and low thermal budget, novel approaches have been and need to be further explored. This paper focuses on rec ent low temperature approaches as combustion synthesis, ultraviolet post annealing treatments which allow their implementation in printable flexible TFTs. Figure 1.
