Abstract Scope |
The rise of additive manufacturing and printed electronics has renewed interest in ZnO as a versatile feed material for piezoelectric and optoelectronic devices. Hybrid 3-dimensional digital deposition (H3D) is a multi-material device fabrication technique which incorporates on-line post-processing and imaging. Within this study, a ZnO precursor, Zinc Acetylacetonate Dihydrate, is formulated into an H3D inkjet-printable ink with consideration to jettability, ink-substrate interaction, and crystal growth conditions, and then deposited into films. Processing conditions of the printed film such as ink film thickness, UV and IR radiation, and substrate heating are investigated to yield in-situ morphological control. Characterization of print film morphological, electromechanical, and dielectric properties is conducted.
