The opportunity to deliver unprecedented material and device performance by utilizing unique properties of nanomaterials has generated tremendous interest in both the academia and the industries. In this work, we demonstrate the successful synthesis and printing of quasi-two and three-dimensional (D) inorganic oxide semiconductors with controlled morphologies on a number of device substrates via an environmentally-benign process. Compared to previously reported data of similar nature, a high Hall-effect mobility (∼ 50cm2V−1s−1) is obtained with our nanomaterial-based inorganic printed semiconductor. Using these nanomaterials, a rapid printing process has been developed to strategically pattern features in the millimeter to submicrometer length scale regimes. We show also the seamless integration of these nanomaterials to obtain high performance electronic devices, for example thin-film field-effect transistors (TFTs) with the printed semiconductor as the active channels. Excellent device performances with high field-effect mobilities, μ eff > 20cm2V−1s−1, and respectably high drain current on-to-off ratios, I ON/OFF > 104, are obtained with our TFTs.

More about this publication?
  • For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
