Abstract

Inkjet printing has become a promising, efficient, inexpensive, scalable technique for materials deposition, mask-less and digital patterning in many device applications. Meanwhile, the ink preparation remains a challenge especially for printing functional oxide materials. Based on the principles of inkjet printing (especially relevant for piezoelectric drop-on-demand inkjet printer) and the process of the conversion of liquid ink into solid thin films of oxide materials, we present two approaches to the design and tailoring of inks: (i) oxide particle suspensions (e.g., SiO2, TiO2, Fe3O4), and (ii) metal-acetates precursor solutions for directly printing oxide thin films (e.g., ZnO, MgO, ITO and forth). The solution inks are stable, and produce tunable oxide films with high density and smooth surface. For some of the inks containing multi-type acetates with possible phase separation even before calcinations, we have developed a chelating procedure in order to tailor the films into single phase homogeneity. The work lays a foundation for inkjet printing of oxides for functional applications in electronic, photonic and energy devices.
