“…In describing the reproducibility and the uniformity of the S-OTFT with the LCP insulator of randomly aligned RMs, eight different S-OTFTs were tested. Note that the uniformity of the TFT is one of critical factors for practical electronic applications [16,17]. The transfer curves of the eight devices were measured as a function of V g from −20 to −50 V at V d =−50 V. As shown in figure 1(b), the drain current levels of the eight devices were largely varied in the range between 10 −5 and 10 −7 A, particularly, the largest variation at V g =−50 V, being an indicative of the poor reproducibility/uniformity of the S-OTFT.…”

We develop a solution-processed organic thin-film transistor (S-OTFT) with high stability and uniformity using a liquid crystalline polymer (LCP) as a gate insulator. It is found that the liquid crystal order in the LCP is one of critical factors governing the electrical properties of the S-OTFT. The photo-polymerized LCP layer exhibits the chain ordering which significantly improves the dielectric characteristics of the insulator layer and the reliability of the S-OTFT. A prototype array of 3×3 solution-processed organic light-emitting diodes integrated with the S-OTFTs based on the LCP insulator shows the high uniformity of light emission during operation.

“…The absence of solvent completely suppressed the exhaustion of volatile organic compounds (VOCs). No VOC emissions are preferred when electronic fabrication is replaced with a direct printing process [84][85][86][87].…”

Electrophotography is a digital, on-demand, dry, and page printing technique that operates based on toner particles of electronic materials using an electrostatic force and generates an electrical circuit via distribution of the toner particles. We developed a 10 μm linewidth resolution with various electronic materials, including conductors, semiconductors, and insulators, without any chemical pretreatments on the substrate films, while a 5 μm resolution was also possible for limited materials. The electrical resistivity of the printed Ag–Ni after an intense pulse light sintering was comparable to that of commercial indium tin oxide transparent films.
